It's not pretty detailed, but the fight choreography is awesome.
The episodes are like 5 minutes each, and the long ones are 15 (because the epic-ness can't be contained in 5 minutes!) lol
It also has good comedy, and even plot!
And the music is pretty good too (I even have the opening theme as ringtone!).
If you haven't seen it, well, you should; or at least give the trailers a try!
Too bad volume one is over, but I'm waiting for more!
