Honestly my main issue with Bleach is the same as any other long running series. Everything is super stretched out. It feels like the show tries to waste as much of your time as possible.

If I recall correctly, Bleach was even more stretched out than the average. The anime was being produced so fast that the (unfinished, at the time) manga couldn’t keep pace, and they ended up shoehorning in a lot of anime-original material, which, however, couldn’t be allowed to advance the main plot or contribute any real character development, lest it contradict the later manga.
