Basically, any emotional outpouring will get me crying, as Truvy said in Steel Magnolias (yup, cried in that one), "I have a strict policy that no one cries alone in my presence."
But, movies (and tv shows) that have not only gotten tear, but a full-fledged body moving sob are:
The Cure: Story about two little boys in Minnesota. One has AIDS and they read about a doctor in New Orleans who has "found a cure" for the disease, so they start down the Mississippi River to find him.
Finding Neverland: When they are doing the play at home for Kate Winslet's character and they ask who believes in fairies. Then, the stick-up-her-booty grandmother starts clapping... I lose it!
Extreme Makeover: Exactly, whenever there is a kid with a special need. And/or when they give out a scholarship. The one that got to me the most was the deaf parents who had a son with no diabilities (he got the scholarship) and a son who was autistic. Pretty much if Pauly is crying, so am I.
Touched by an Angel: OMG, the one where Wynonna Judd played Audry. Her son way dying and he made a list of things he wanted to do before he died. The angels came to help him complete the list. The last thing on the list was "Help Mom finish the song." Which was a song she had started when he was born, but stopped writing when she found out he was sick. Needless to say, she finishes the song and Andrew takes the little boy to heaven as she is singing it to him.... Damn, I'm starting to tear up just thinking about it.
I think that a good cry is very cleansing and good for you.
