Since I never go out to the movies, short movies don't bother me. I like owning movies of various lengths so I can squeeze a movie in before bedtime no matter how late it is.
I had to laugh when the movie "Following" ended though. There were all these great twists and turns about 55 minutes into it and I thought "oh my god, what's going to happen next?" **Zhora sitting on the edge of her seat** Ummmmmm, nothing? It ended at the 1 hour mark.
