Lance it scares me every time we agree, and I can't believe Miami Vice is one of those times. Its complex, and not as action-oriented or as involving as mass audiences wanted, but there's real talent behind it, and it takes more than one watching to see the whole picture. The first time I saw it, I liked it for the action and cinematography and was reasonably interested in the characters, but I did think it dragged, and that the plot was purposefully convoluted to cover up not really being about anything, but I caught on a lot more the second time (the first time was really late, and I eve dozed off in the theater a bit haha). I appreciate the kind of screenwriting that doesn't give exposition, it just drops you into a story, because exposition is only ever clearly written for the audience, it takes away from the realism. Its the main reason why I like this screenplay, and why I love Susanne Bier's films like After the Wedding. The story and its characters are just organic, not constructed in front of you.
As for Public Enemies, I think people are missing the point, both Purvis and Dillinger were two very isolated and not understood individuals despite their huge fame, I think that's what the screenplay meditates on, and the hero-worship of an outlaw. Even the audiences for this movie are probably rooting for Dillinger more than the FBI. We really won't understand these two characters all that much, and so Mann uses them as a vessel for putting us in the shoes of the American people during the time period, and makes a very interesting topical display of the lengths to which we should go for law enforcement. However, Hoover while well played by Crudup, was a drawback for me I feel the movie only adds to the one-sided maligning our culture now has for him, like claiming he had no field experience, which is untrue. I was skeptical of Mann using his 2000's era grit for a period piece , it surprisingly worked, even using the weird video feel during quick-motion in low light to give those moments an unsettling edge, it was bold but I think it payed off. And it was electrifying to see the real crackle of Mann's gunplay in the period/true-crime setting, the scene in the woods rivals his best from Heat, and the climactic shootout in Miami Vice.
It could have been a bit tighter, but its not the one-note missed opportunity people seem to be crying about (or echoing critics about).
Also, to me Mann's best film is The Insider, an incredibly taut slow-burn character film, and perfectly rendered true story. Its quiet, and not for those who only appreciate Mann as an shootout maestro and creator of Miami Vice I guess. And to me some of the best directing of actors he's done was on Last of the Mohicans, so its hardly true to say he should stick to crime movies in LA. I applaud him when he tries something new, like with Ali, another wholly misunderstood movie.
For me:
Insider
Heat (a hit with mainstream audiences for pairing De Niro and Pacino and featuring killer action, but it is the best in-depth analysis of cops/robbers out there, and just a brilliantly written film. Pacino's finest role of the 90's I think, and even De Niro isn't over the top.)
Collateral (the thriller of the decade as far as I'm concerned, electrifying style, unnerving/different performance from Cruise, and an excellent/vulnerable one from Jamie Foxx)
Manhunter (a gem of an early effort, and my favorite portrayal of Lector, because he's unnervingly believable as a real person, and he's not the central character, the way the book intended. Whereas Hopkins' later performances were amazing for a screen-villain, but there's no way you'd ever believe there could be a person like that, and the screenwriters shifted too much of the focus on him.)
Miami Vice
Public Enemies
Ali
Mohicans (that said I still love these last few, they're just a little more ambitious than they can pull off)
Thief
