Bumping this...
I wanted to address a few of the complaints I often hear about the PT that I disagree with. You can never enough points of view...
1."They weren't needed in the first place"/"There wasn't enough story left to tell after the OT to warrant them"/"The OT gave us all the information we needed"/"Any questions that were left unanswered in the OT were just curiosities and not important or relevant enough to the story to warrant prequels"
If "how did Anakin become Vader", "how did Luke and Leia get separated", "what happened to the Jedi", "how did the Emperor come into power", "what is the republic the rebel alliance speaks of", etc, are not big enough questions to warrant prequels, I don't know what are. There was so much vague backstory and unanswered questions in the OT, I don't see how you could love those films and NOT want to see the backstory filled out.
2."There's no story in the prequels, it's just a special effects showcase with no depth and no charm"
I don't understand this one. There is plenty of story in the prequels. The story of how Palpatine used a trade dispute and Anakin's niavete to jump-start his manipulation of the entire galaxy. The story of how The Jedi met Anakin by chance and how Anakin managed to get off Tatooine and out of his poor upbringing and into the life of a jedi knight - in - training. The story of Obi-Wan training Anakin. The story of Anakin and Padme's romance. The story of how Palpatine manipulated the clone wars and how he ultimately controlled both sides in said clone wars. The story of Anakin's seduction into the dark side. The story of the way the "Old Republic" was. The story of how the Jedi fell. The story of how Darth Vader the human(after falling to the dark side) became Darth Vader the 'more-machine-now-than-man'. The story of how Luke and Leia were separated.
As for the 'no charm' thing...I think that's more to do with the fact that there's no clear person or people to root for throughout the PT the way there was with Luke/Leia/Han than with anything else. There were no characters to fall in love with instantly like that. The characters were more layered.
3."The whole concept of midichlorians ruined the whole concept of why the Jedi were Jedi"
People insist that in the OT it was at least implied that there were magical and/or mythical elements in 'the force' and the status of being a Jedi. The OT I know tells the story of how Luke and Leia are the only Jedi left after Obi-Wan and Yoda die and that they are Jedi because they are Anakin/Vader's offspring. This premise, which cannot be disputed as far as I can see, which is at the center of the OT, leaves no doubt that being a jedi, and having the ability to control the force, are biological in nature. So I don't understand how the concept of midichlorians ruined anything or even changed anything. The OT gave no reason to think being a Jedi wasn't simply a very rare biological condition whereby one had the ability to control the force. By my understanding, 'Midichlorian' is just a term, a name for living cells that exist in everyone, and those with a high number of them can control the force and therefore are Jedi. It doesn't change anything from my point of view other than to introduce a unit of measurement for how strong the force is in any given Jedi. The nature of being a Jedi, imo, wasn't altered at all from the OT to the PT...it's just that in the OT it was left to us to figure out after learning that Anakin/Vader is Luke's father and that Leah is his sister, and in the PT, TPM to be exact, it was explicitly said(by Qui-Gonn and Obi-wan to Anakin's mother).
4."A lot of the PT was irrelevant to the OT"
I think every last bit of it was relevant. Some say the pod race in TPM served no purpose. I say that it, along with the depiction of the slavery of Anakin and his mother, served the purpose of showing Anakin's beginnings, of illuminating the core of his character, of showing why later on he tended to show resistance to authority, why he tended to have a chip on his shoulder, and why feelings of inadequacy and repression born from not only being a slave but watching his mother be a slave might have given him a thirst for the power to destroy any and all of the forces that were responsible, directly or indirectly, for making his early life what it was. The pod race paid for his freedom and for the parts necessary to repair the ship that Qui-Gon and Obi-Wan had come in. The pod race was Anakin's ticket out of the enslaved poverty he was living in, and his ticket to the opportunity to make a better life for himself and for his mother. Also, having to leave his mother behind only made him hate the forces that held her captive even more, and this is shown later when his rage at her death causes him to go on a rampage to avenge her.
Some say that the politics of the Old Republic are irrelevant. I say that they were crucial to painting the picture of the galaxy before it was taken over by a dictatorship against its will. The Phantom Menace itself starts in the middle of the story. The Old Republic is peaceful and functioning. Planets have business with each other and disputes with each other. They trade with each other. They co-exist with each other. All of the political elements of the PT show us what LIFE was in the galaxy pre-empire. It gives us a clearer understanding of what the Rebel Alliance is fighting FOR in the OT, of what they feel was lost when Palpatine established the Empire, and what they hope to regain with a victory over the Empire.
Some say that the Anakin/Padme romance didn't need to be on screen so much. I say, if nothing else, it served the purpose of allowing us to see who Luke and Leia's mother was, which is relevant to the OT when you think about the fact that Luke and Leia DIDN'T know her. The fact that she, along with Bail Organa, and other senators at the time, started the Rebel Alliance, the group that won the hearts of so many in the OT with her children at the forefront, also adds a layer of poignancy.
Some even say that Order 66 and the Jedi Purge are irrelevant to the OT. The whole OT leads up to the return of the Jedi. The return of the Jedi takes on a new level of significance when you find out why they were gone, and when you actually see the Jedi getting executed at the end of ROTS. Likewise, Obi-Wan's exile to a cave on Tatooine and Yoda's exile to Dagobah are given much more weight when you see why they had to exile themselves, why they had absolutely no choice after Palpatine took over - it was either run and hide in obscure lands or be killed. They were forced to leave their lives as they knew them in failure. Their mistakes and misplaced trust had played into Palpatine's hands, and they would have to live with it for the rest of their exiled lives.
To me, the prequels add a whole of depth to the OT because they allow us to simply KNOW more about what is going on. When we see "Old Ben", we know why he seems so weary and tired and sad. When we see Vader, we know who he was as a young man before falling to the dark side. When we see Palpatine, we know how he got disfigured, and how he became Emperor. When see Luke being curious about his mother, we know who she was. When we see the Rebel Alliance, we know who started it and why, and we know exactly what the kind of Republic they're fighting for is. When we see that Leia is a princess, we know what she was a princess of and why. When we see "Old Ben" and others talk about this extinct people known as Jedi, we know who some of them were now - Qui-Gon, Mace Windu, young/younger Obi-Wan, young Anakin, the others on the Jedi council, how little children were being trained to be Jedi, etc - we know who they WERE now, and we know what they believed in, and what they fought for in their prime, and therefore we can notice the absence of the Jedi more, and when they 'return', there is that much more satisfaction.
I'm not saying the prequels are perfect. I don't find Jar-Jar quite as annoying as many do, but I do understand why many would question his purpose. I understand why many feel that the romantic dialog between Anakin and Padme was sometimes cheesy and wooden. I understand why many feel that Anakin's 'fall' happened too quickly. I understand why many feel that the PT was too 'kiddified'. But overall, I don't think any of this is so bad that it should ruin the PT. There's just too many great moments, imo - Qui-Gon and Obi-Wan's 'arrival' on the trade federation ship at the beginning of TPM, the pod race, the Qui-Gon/Maul/Obi-Wan duel, Obi-Wan taking Anakin under his wing, the arena battle in AOTC, Yoda fighting Count Dooku, the Anakin/Obi-Wan duel, Vader rising in the suit for the first time, the Yoda/Palpetine duel, the Jedi-purge, etc.
I just think that the PT could've been a radically different set of films and it still wouldn't have been accepted and/or liked by a lot of people simply because they are interested in any Star Wars story that isn't the OT. Which is fine, I guess. There are plenty of people that love the original Star Trek series and don't care for any of the others. But don't rip the PT if you aren't interested in any Star Wars story outside of the OT. Perhaps Lucas's biggest mistake was his insistence on trying to make the OT and the PT into one thing...not wanting to release the Original OT on DVD, wanting to package all six together. I say this because I think a lot of people simply don't like the way Lucas has tried to re-center the whole story on Anakin. I can't help but think that if Lucas marketed the PT was simply a backstory to the OT, rather than try to make it one big saga, there may not be such venom against the PT. I personally like the idea of one big saga, but I can understand those who have been Star Wars fans from the beginning resenting Lucas's attempt to re-center the story. I also understand the resentment these fans have regarding the changes made in the special editions of the OT. I personally don't mind the changes so much - I think they offer an interesting alternate take on things - but I do think Lucas should have made the original OT available at the same time the special editions were released, or better yet, put them in the same package as double-sided dvds, instead of only doing so after fan outcry, because otherwise he is taking the choice away from us. I don't have a problem with him wanting to make changes to his films as much as I do with the fact that he wanted to force everyone into watching those versions of the films. And given the fact that the alterations he was trying to force everyone to watch were done mostly for the sake of continuity with the PT, I can understand how that would create a lot of resentment and backlash towards the PT.
But really, I think they were worthwhile films, and not nearly the pile of garbage so many make them out to be.
P.S.And just for reference, I'm 23 years old. I saw bits and pieces of the OT on TV when I was little, in the late 80s and early 90s, but I didn't really watch the OT beginning to end and become a fan until the first special editions(which didn't have that many changes in them) were released in theaters and then VHS in 1997. I saw the prequels in the the theater and I never had the bad reactions that many others did. My friends and I loved all of the prequels, and my appreciation of them has only grown, despite its flaws. I own the 2004 OT box set, burned copies of the Original OT dvds that were released after the enough fans demanded them(they were only added to the 2004 box set and I wasn't going to pay for something I already had so I got the Original OT discs from netflix and copied them), and the prequel dvds.
