The thing I didn't notice when watching Z and notice all the time in Kai, is how all those episodes are cut right out! All the well drawn/animated episodes almost all in tacked, back to back (pretty much).
So this is where I really noticed it: On the episode where piccolo goes up to God and wants to merge with him. The good animation is playing, goes to a short moment of Last house that lasts like 2 minutes and then back to a well animated episode again (but in Kai it's all in one) This isn't distracting, but I that means all the crappy animated episodes have all filler and everything important was done by the better studios (makes sense right?)
Last House, I guess, followed the manga for a bit with mostly filler in their episodes. One thing I would like to see is Dragonball without Last House but then again, DragonBall was worse than Z by spamming Last Houses studios in ALL their episodes!


Last House's Vegeta in the Cell saga... yeah
