Well, I completely disagree on the blood thing though. I'm a very big adult swim fan...mainly because it's the only thing I can watch when I stay up late. ([sarcasm]THANK YOU DIRECT TV BASIC PACK[/sarcasm])
Compared to TV series like Paranoia Agent, and Samurai Champloo, I'd say that Bleach has a lot less blood, and most likely it'll all stay in there. And on the part of voice acting it should be good. Viz has a way of casting good voice actors (except for Naruto's case, where I'm pretty sure it was a good idea to hand it over to another company to stop from ruining their image).
And as always, I expect the extra, and usually, 'useless' dialogue.
...like the dialogue in this paragraph.
