I haven't seen a few of those but I've never cried at a film.
I have, however, become VERY close to crying in four episodes of television. The first was an episode of Buffy the Vampire Slayer called "The Body". If anyone has seen this episode they know exactly what I mean. Tragic, heartbreaking, brutally realistic. The second and third are both from Buffy's arguably superior spin off: Angel. One was in an episode called "A Hole In The World" and the second was the last part of the finale, "Not Fade Away". Towards the end the death of a main character done in the most beautiful yet heartbreaking way that I almost tear up every time. The final episode was from Lost when Desmond and Penny are on the phone together.
