TheBlah
One of the great modern classics.
Combat animations are good, music is alternative&unexpected but manages to fit the show, sound is ok, characters & story are very good.
All in all, it's not something that will shock you, but everything fits very well together and flows very well. "Re-watch" potential is not very high but soon or later you're going to miss it.
Watch it if you liked "Cowboy bebop".
