I cry at movies. I admit that. I cry at Pixar movies.
Monsters Inc - the ending, one word "Kitty!" Tears.
The Incredibles - The Elastagirl getting shot down scene, the following "I'm so proud of you" to Dash scene and apology to Violet scene.
Toy Story 2 - the scene with the Sarah McLachlan song over it. Total tears.
Finding Nemo - Dory's "I'm home" scene.
Ratatouille - Ego's flashback scene and his monologue at the end.
Wall-E - The beginning gets me. The "Put on Your Sunday Clothes" song over the devastated city scenes just blows me away every time. Tears.
Up -
But I didn't cry during
Cars (if Lightning McQueen was likable [imho] then I might have cried at his heroic deed at the end),
TS1, Bug's Life...
I think the 3 movies that made me cry the most are
The Fighting Sullivans,
Brokeback and Milk. I had to call my bff Julie after
Milk. I was sobbing trying to drive home from the Sherman Oaks Galleria. She's my rock.
