Have seen Bleach until the start of the arc after the soul society (the one with Ulquiorra and Grimmjow). Was very good but for some reason I dropped it (probably wasn't in the mood for a long running series). Now that the anime hasd finished I will probably watch it again when I have time.
Definitely worth it, the new seasons have had a massive jump in budget so that helps. Theres a lot less humor and a lot more serious tones. I do miss the jokes sometimes, but theres not really any times where theres any room for that. Its pretty non stop action.
