What I found awesome was Ichigo Hollow form was about to fire off a Cero at 'Love'. Too bad he didn't get to fire it. >>; I wanted to see the Destructive power of a Cero. *sigh*
Each of the Vaizards are pretty interesting and their powers are intriguing. The many kekkai (shields) that the fat one put up were all very interesting in my mind. That chained pillar one was an especially high leveled one I remember. Too bad it broke. ^^;
Now, I'm just worried about Orihime. I actually like her character and the OP is making me nervous. -.-
Oh, and that last part of the episode about Karakura Town being the target for making that key, wasn't it obvious? xD
