Oh, yeah, I never cared to read the manga. Barely cared to watch the anime to the end
Bleach started strong, had a horrible filler, then repeated it's self, finally climaxed, and then kept going, and rushed some elements that would have been better in a light novel of something, and then it had a whole other third major arc (manga-only), with an increased amount of trolling to try and stay interesting, and then it became canceled and had to rush things. >.>
You could probably get away with cutting a huge chunk of things out, maybe from Aizen's flip to the direct invasions with maybe an episode or two to summarize some things like the Vizard.
