Actually, the best part of Bleach were the first 15 episodes or so, the balancing school with being a shinigami stuff. After SS it took a trip to Namek and hasn't come back.
Although the manga's getting pretty interesting atm with the flashbacks. Anime still had like 900 more fights to catch up, fights no doubt filled with QUALITY animation. Heck, if doing filler means they have a better budget for the Kenpachi/Noitora fight so it'll be as good as the Grimmjaw/Ichigo fights, I don't care.
