I never saw the movie. A guy at work was telling us about it after opening weekend and he described some guy raping another guy. The rest of us were cutting disapproving looks. I decided I could skip that movie and life has worked out just fine for me without watching it.
I'll admit that it's been a very long time since I saw Pulp Fiction, but I sure don't remember a gay rape scene. Maybe I was half asleep at the time.
Honestly, I thought the movie was interesting in a quirky sort of way. It was a real departure from standard movie making of the time, and definitely not Oscar worthy material. Still, it has become a cult classic.
