Personally, The Rocky Horror Picture Show.
I knew it was going to be quite the experience before I went for the first time‡ but it was so much fun I had to keep going back bringing friends each time.
It's still a fun tradition to do though we haven't done it since last year, we're probably going to try and go again in a few weeks.
‡ I had seen it many times before going to see it in theaters for the first time.
I actually walked out of Schindlers List and bough a ticket for the very next screening.
Bleak as hell but I’d never seen a film that locked me in the way that film did.
Why did you walk out? Did you not want to see the ending the first time?
I thought it would build anticipation.
