Bleach is really great, but it has a couple of problems.
Nobody ever dies. Regardless of how much they get cut up, shredded, or whatever. They'll "die" but then they'll turn out to be okay two episodes later.
It's pretty slow to develop. It reminds me of Dragon Ball Z in that they can often drag things out. It's nowhere near as bad as Dragon Ball Z is in this department, but it's definitely there.
