I am currently rewatching bleach anime because I thought they went into a long filler season. Looking on the bright side, at least I did not have to wait every week just to watch Bleach. i can watch them at one go which is now re-entering its filler stage anyway. Fighting Aizen was awesome because he is still one of the strongest villains in Bleach. Not only he is the strongest, he is also one of the coolest.
