I haven't seen...

I'm somewhat of a movie buff and yet I've never seen Rocky Horror Picture Show. I've heard it referenced to on shows like Gilmore Girls. I can never find it at the library or video store and I don't want to make the commitment to buy it. I hate buying movies that I haven't seen yet because I never know if I'll like them or not. I know, that doesn't make a lot of sense because then I miss out on a whole wide world of movies but it also saves me from being embarrassed by the shelves on my entertainment center. It seems like one of those movies that you either love or hate and I won't know how I feel about it until I actually see it.
