The summary makes it sound like a serious movie, but there are also some funny moments in it as well. It is not your typical story with an emotionless assassin that tries to look cool all the time. What I really liked about the movie was that it was told from the four hitmans perspective. Their personalities and habits were really entertaining. I really liked the fact that one of them was narrating some parts. The characters were all well shaped out and the actors did a good job portraying them. I think this movie is worth watching because it is funny, has action and some emotional development from the characters. The mix seems just right.
