TV is a different story, but possibly only because I watch much more TV, so there are more chances. I've cried many times over Doctor Who, and still do - outright bawling at the ends of "The Family of Blood", "The Last of the Time Lords", "Journey's End", and "The End of Time", every time I watch them. I know the first time I saw "Doomsday", I cried, but it's completely lost its punch. Interestingly, since "The End of Time", I've had almost-tears moments but no outright crying for four seasons now - the closest was "The Doctor's Wife". I also tear up every time in "The Day of the Doctor", when Ten and Eleven join War to fire the Moment. Hm - I saw that in the theater, and I'm pretty sure I cried then, so there, I cried in the theater.
The most recent sob was at the end of season one of Arrow, when Tommy died - my favorite character on the show and such a tragic death.
