As a kid...
ET
Fox & the Hound
Bambi
Snow White
Old Yeller (nobody else cried when Old Yeller got shot?)
This TV movie about a whale (I think there's a book too, and it's a true story). The whale got trapped in this little bay-type thing up in Newfoundland, guess it was a high tide, and everybody in town is torturing this whale...shooting at it with little piss guns, spearing it etc. And this nature guy is trying to keep the whale alive until the next spring tide so it can get free, but she doesn't make it...when the whale died I bawled like a baby.
Now...
Dead Poet's Society (the O Captain scene in the end)
The Green Mile (when Coffey gets executed)
Field of Dreams (when he asks his dad to have a catch)
Rudy (when Rudy gets into ND, and again when the players are laying their jerseys on the coach's desk)
Titanic
...can't think of any more now, but they're there...I'm a big sap when it comes to movies.
Oh and Extreme Home Makeover? My wife cries in every episode.
