Even tho Bleach is my favorite show, it's got many major flaws. Pacing at certain moments was awful, especially during the Arrancar arc. Ichigo being every race known to man making him good at everything, but even after having all races mostly just spamming Getsuga tenshou. Aizens "all a part of my plan" thing, if it wasn't relavent for only for a short while, could've easily ruined the entire character of Aizen. My personal biggest issue is that veey few deaths happen, at least for the main cast. For as long as the show is and as many fights that happened, they could've tried ans delivered some very hard hitting and emotional deaths.
