I was completely unprepared for how sad Up was. Sat down expecting a comic cartoon then the story of how the lonely old man used to be young, fell in love etc etc etc. It didn't help that I was pg at the time and it was far too close to real life (you know, until the house takes off! :) ).
I sobbed my heart out. I'll never watch it again. Mind you, I am a sissy, cry at lots of films.
