For some reason, I love a good weepy movie. If a movie can make me feel happy, break my heart, and then make me happy again, I consider it a masterpiece. Disney seem to be particularly good for this.
The fox and the hound gets me really bad every time.
Some others off the top of my head
lion king
the lake house
charlottes web
the pursuit of happiness
titanic
saving private ryan
forest gump
moonlight jellyfish
What movies make you guys cry? Or at least well up 😛
