If you are a friend of funny, thrilling and bizarre movies, you're gonna love this one! First of all, this movie manages to surprise you again and again till the end. It switches between funny, dramatic and thrilling elements. James McAvoy gives an amazing performance (by far the best I've seen from him) as the funny, manipulative, sick, drug-addicted, broken, Cop and manages to portrait every aspect of the character. Another piece of awesome acting is delivered by Jim Broadbent who plays his psychologist. The dialogues between him and James McAvoy are just amazing! The rest of the cast is also decent and the characters are all very special in a refreshing way. The only bad thing i can mention about this movie is, that it has some (but small) longueurs. I can recommend it to everyone who likes movies of this kind and has no problem with movies containing a lot of sex, drugs and f*cked up moments :)
