I don't think hitman stories are overused. "Golgo 13" is the reason why I think this now. This movie was cool. It's interesting how people can make an animated movie, and treat it like a movie with real actors. Cartoons were never supposed to be like this. I was impressed. The action scenes were thrilling, it had great characters, and it was well acted too. The drama was actually strong in this movie. We focus on the father of this one person Golgo 13 killed, (It's not the whole movie. We focus on Golgo 13 too.) and it's strong. We see how bent on revenge he is, and it shows that your not just watching this for violence. If you like Japanese anime, then you'll like this one.
