I'm going to go watch it now... and I think you might want to put a "possible spoiler" on the title just in case.
EDIT: Okay, I watched it. Erm... I'm a tad bit disappointed in the ending. It seemed to have been rushed? I get how it's more of a psychological battle but I really wished there was a bit more action. >< Taku just sort of suddenly gained these 'super powers' and beat the hell out of that guy.. D:
