I am not a crier. It's not that I have anything against it, it's just not something I do often, so when a movie can actually make ME shed a tear, I consider it a grand achievement. That being said, weirdly enough, the only movies that have ever succeeded in making me cry were animated films:
Toy Story 3 (the first time I watched it, I was practically bawling from about the last 15 minutes of the film until about 30 minutes after the film ended.

)
Up - I defy anyone to not get emotional during the first 15 minutes of that movie. Also the ending is so sweet
with the two sitting on the curb eating ice cream I couldn't help but get teary-eyed all over again.
Iron Giant - "Su-per-man. *eyes close*" Me sobbing.
Wall-E - Didn't really make me CRY, but the part near the end where
Eva finally repairs Wall-E, but he's not the same Wall-E anymore
broke my heart, and almost got me going, but didn't.
Sometimes I think Pixar was created to make adults a weepy, blubbery mess. Anyway, I feel like there has to be at least ONE live action film that made me cry or at least teary-eyed, but I honestly can't think of one.
