We pretty much have exactly the same opinion. (aside from liking Byakuya best I guess, lol)
One thing I've
noticed with people who are big fans of Bleach is that they tend to have a huge priority in a few categories, namely:
1. Awesum battles
2. Cool poses
3. Percieved depth/maturity
4. "cool" characters being the focus.
I think you're spot on in saying Bleach is pretty much DBZ with a thin layer of pretentious "depth" thrown over it. However this might ironically be it's strongest selling point.
In a way I don't see Bleach as a story as much as an attraction. There's a few base plot lines to carry the series along, but if you honestly assess how relevant these are to the story as a whole, most conveniently vanish in favor of battles.
A great example for me has always been the fact that the introduction of Bleach shows how Ichigo is capable of seeing ghosts. Remember the last time this was in any way relevant to the story? I sure don't.
But one thing I've started to realise about Bleach is that it genuinly isn't trying to tell a traditional story. Stuff like Ichigo seeing ghosts is just build up to the next fight scene, rather than something that
could stand on it's own.
Now you could argue this makes Bleach bad, and I'll be honest, if you evaluate Bleach's main story while taking out the fighting ... yeah, there's pretty much nothing there.
But I think that in the eyes of a lot of big fans of Bleach this is hardly an issue. I'm personally reminded of the negative sentiments people had towards some of the flashbacks during Fishman Island. Most of those flashbacks had little to nothing to do with awesome battles or anything "cool", they were extremely story driven. And to be frank, this flat out repelled some people.
Heck, it took every single Straw Hat executing a page-spread super move for people to shout "ARC REDEEMED!", just some cool poses and badass attacks, nothing of story significance.
I'd like to think that people who super duper love Bleach the most ever forever see "too much story" as extra baggage that ruins their clean, fun shonen battle experience. It's not a coincidence that these same people tend to complain about how crowded One Piece chapters are. How can you dedicate half your pages to badass fighting poses when there's so much plot and story on each page.
I don't particularly like Bleach at all, but I can
understand how different priorities can make the series a lot better for some people.
Anyway, that's just how I see it in a very generalized way.
