>>11063400 grimmjow vs. ichigo part?
While that part was pretty good compared to the stuff prior to it, it was average at best compared with a lot of Bleach's earlier content.
Bleach went into a massive plotless slump immediately after Ikkaku vs. Edorado, started pulling out of it with Grimmjow rescuing Orihime, and didn't really get back on track until Aizen attacking Karakura and the current flashback.
This is all from the manga of course. The anime has been downright unwatchable due to horrid animation since the Bounts entered SS. With the strange exception of the Ikkaku vs. Edorado fight, which was just as good in the anime as it was in the manga.
