I've never walked out of a film, however, I do vet what I watch quite strictly, especially if I'm going to watch it in the cinema. However, once I've started watching a movie, I like to stick it through and give it a chance.
Anyway, I saw Audition in the cinema with my newly acquired boyf at the time and it was the first movie we'd seen together. Probably not the best choice in that situation... However, I thoroughly enjoyed it... but I think there were at least two couples who walked out towarRAB the end....
