A remastered HD recut of the Dragon Ball Z anime, with redone and improved dialogue, improved animation in some cases, a
new soundtrack (although this was considered lackluster to many, resulting in
projects featuring more familiar soundtracks from DBZ), and almost all of the filler that slowed down the pacing of the original
show is cut out, resulting in 167 episodes instead of 291, with many scenes and events that notoriously took up several episodes (such as
Goku running down Snake Way taking a full 12 episodes) compressed into fewer episodes. It is meant to be much closer to the original
manga's pacing. It is considered by some to be the definitive DBZ experience, while original elitists consider it an abomination.
The
4Kids version of Dragon Ball Z Kai was heavily censored, with all swears, blood and a lot of the more violent scenes removed, along with ridiculous censors such as Mr. Popo being colored
bright blue instead of normal black, and should not be considered the
true DBZ Kai version.
