It sucks you in right off the bat and when the two main characters pit themselves up against each other, you feel as though you're right in the middle of them. It really stimulates your mind and even when you think you're one step ahead of the characters, they knock you backwards.
Towards the end, it fell slightly short in some episodes, but nevertheless, a truly fantastic piece of art! I almost NEVER re-watch anime, but I have done so with this one 3 times over.
The two main characters are definitely two of my favorites ever and make the show worth watching.
