The Tsuiokuhen was great, and it's the best part of the anime, imo. For the main series, after Shishio (sp) it gets so boring, that it should have ended there (well, yeah, Shougo was nice, but that's only 5 or 6 episodes).

The Seisouhen was crap. Really, that wasn't necessary. And sometimes it made no sense at all. Maybe there's something in the manga that explains all that crap. Otherwise, it's just a lot of drama to end the series.

The movie is good too.
