There's no other way to say this...
That. Was FUCKING COOL.
Like someone below me said, you should check out SMBZ. You have the potential for a great series here... now you just need a story and perhaps some voice work... If not, you can do what they do and piece together sound clips. I kinda expected at least some clips of the shinigami yelling out "BANKAI!" somewhere in there... I can't quite give this a 10 for that reason. Sound is important, and while the song was pretty awesome, at least some spoken dialogue would've been good. If you need info on some good clips, look up the bleach DS games, they've got voicework from MOST of the original voice actors, I think (depending on whether or not you're going off the English versions... I know some people don't care for the English dub or it's voice actors, but I happen to like Johnny Yong Bosch's work with Ichigo.)
