I just watched a German movie from 2005 called Antibodies. It was quite amazing, to be honest. I highly recommend it. You can watch it on Netflix streaming at the moment. As I was watching I was thinking "this is quite predictable, but it sure is keeping my interest" and then it wasn't really that predictable after all. I don't want to give too much away but if you like a good murder mystery thriller then this is for you.
