Several, actually.
Blast from the Past
The Talented Mrs. Ripley
Blair Witch 2 (stationed in Japan, not many movies came, so we saw everything)
Passion of the Christ-Too much for me, I was sobbing, couldn't take watching it to the end.
nope
it costs more than our car payment usually to go to the movies so i'll sit and enjoy my popcorn if the movie is that bad.
OMgah, The English Patient. I felt it just draaaaaaaaaaaaaagged on and on. I know it was Oscar nominated and everything but...yeah.
We went to Rock of Ages and we both absolutely HATED it. I think we made it about 50 minutes and then left.
Benjamin Button. We didn't see it in the theatre, we rented it but I thought it was worth adding to the list. It was the most boring and long movie. I don't know how far into we stopped it, but probably before half way (of this 5 hour movie... or so it seemed!)
A movie called 8mm starring Nicolas Cage....that movie was disgusting and awful and we left less than half way through.
