If you want to find other stuff based on stuff you like, then there are a few options for you, and the latest of these is Itcher. Basically you give it information on things you like; Films, Books, Music and Games. Start with a minimum of 5 recommendations of things that you like, and it pops up more for you. obviously the more that you add, the better the recommendations that you'll receive.
It worked ok for me, but I was confused at times because I thought I was rating things and it turned out that I wasn't. It also didn't find some obvious films either. However, it's worth trying out.
