I think I was expecting to much from DB Kai, but it was nice to watch after all. Not that much, just a remasterization of the original DBZ, with lots of the so called "fillers" removed, making the 200 episodes (end of Cell's Saga) go to 97 episodes.
Violence was somewhat restricted, minimizing blood on some scenes and the animation was smoother, but nothing too special or different from the original work.
I give 9 for the efforts and hope this work could help on bringing a new DB series someday in the future.
