It almost seems like they're doing the Disney thing where they're trying their damndest to hide the fact that the show was originally a hand drawn, cell animated show but they're also weirdly inconsistent about it.
Quick thoughts on the original Dragon Ball: it's great.
I also watched DBZ during its original (and VERY long) Toonami run though I didn't really make the show appointment viewing for me until just a little bit before the start of the Buu saga.
My history with the series prior to now is that I was actually one of the people here in the states who watched some Dragon Ball during it's very short stint on Fox Kids in the early 90s. So I just recently went through the entirety of Dragon Ball (didn't make a thread for that as one had already been made recently so I just commented there) and after finishing that I decided to dive into DBZ Kai.
