Actually that Snake Way crap was all filler, it never happened in the original manga which is y it isn't in Kai since it follows the manga more closely. But I feel u to a certain extent, it cut out a few things that made no sense just like Goku using Kaio-Ken on Nappa and he's holding him up while the camera scales back to show him over his head. Little things like that tick me off. It even doesn't show physical contact when someone gets hit. (Maybe because I'm watching it dubbed)
But on the other hand I do like the extra scenes that it does shows. I noticed it a little bit in the Saiyan saga but it rly becomes noticeable in the Namek saga. Which I appreciate bcuz if it is following the manga, I now know the Dragon Ball Z story the way it was originally told since I've never read it.
