I thought Buu saga was the worst saga DBZ has offered. The series really "jumped the shark" there. If anything, it was nice to see those characters one last time.
I loved it at the start. A whole deal of new story was going on. Majin Vegeta vs. Goku, Vegeta's death, the kids were going to "fuse", Gohan was training to become a stronger warrior, Goku acted like an Obi-Wan Kenobi. Great stuff. But story-wise, it was ruined by the time they decided Buu should absorb people. Then, it really fell apart.
Anywho, you have to realize that the whole Cell saga is consisted from the episode Metal Freeza appears until his death and the Afterlife Tournament.Despite what the Americans have done with the show, the categorizations and all, that how Toriyama saw things, really.
Oh, well....
