This anime is very interesting. The plot is mysterious from the very beginning to the very end. There are many scenes that make you think about the meaning. Some people would call it philosophical problems. It has even more powerful effect because of the whole atmosphere of this anime. I finished it today so still have to thing about some things. The ending was kinda epic.
People who don't like blood and characters dying shouldn't watch this. It is not bloody massacre but the whole anime is somehow dark and full of murders. I was glad to watch finally anime where weapon is not just a toy and where villains are not there just to confront the main hero and lose.
Very important thing for me was that a big part of this series is set in Czech Republic, my homeland. They did quite a good job with Czech texts and even spoken language. However I had to laugh many times :D.
And about the length, people say that this anime has in fact no fillers. Yea I think I can agree. 74 episodes but all of them somehow related to the main story with something new and important for the plot.
So the result: This anime is exceptional. So long and yet so valuable. Watch it, if you are looking for SERIOUS anime.
