I cry at movies almost more easily than at actual life events. I don't know why.
The last movie I saw in theaters was Iron Man 3, and I made it dry-eyed through that one, but before that...Wreck-It Ralph. And oh my, I wept, wept when Ralph destroyed Vannellope's racer thinking that keeping her out of the race (and breaking her heart, each of them losing their only friend in the process) was the only way to keep her alive. She's screaming and crying, he's at the lowest point in his life trying to do the right thing and it just destroys me to watch.
Other movies I can remember crying about in the theater? The last three Harry Potter installments, Lilo and Stitch (basically a movie about orphans trying not to get separated by social services), Return of the King, Big Fish, Serenity...
I'm worse with television series. I cry at every third episode of Doctor Who, and some even on rewatching will get me going for ages. I cried thrice during the Office season finale, the second time I watched it. I cried for Jim & Pam's wedding. I cried for Joyce Summers in Buffy the Vampire Slayer. And again at that show's finale, mostly for Anya. I The past I-don't-know-how-many episodes of Warehouse 13. Certain episodes of Scrubs, and that one Futurama about Fry's dog. Torchwood. Every time Xena Warrior Princess thought Gabrielle was dying.
Basically, I'm a fountain.
