I remember along time ago at Retro Junk I read an article concerning that animated adult film from the 1980's called Heavy Metal. The writer has only watched it a few times since he saw it as a kid, only breaking it out on occasion to watch.
Do you have one of those types of movies? A special occasion movie that was part of your childhood and you only watch from time to time to relive those memories?
The only one I would say as of now for me is Project X. I remember Project X being pretty big at my high school when it came out a few years ago. Everyone was talking about it and how you needed to see it. After catching it at the theater, I've only seen it one other time, which was recently, and which brought back some fun memories from that time in my life.
