I liked the episode, (the last one too, although Toride-Vendor was meh) and Dr. Maki is pretty awesome. He's one interesting character!
Anyways, this episode had a pretty good plot, and it's nice to know more about Gotou, but the camera work was pretty lame in some scenes. And EIJI PLEASE STOP USING CHEETAH BECAUSE THE EFFECTS ARE HORRIBLE.
Also, I think we're getting full combos too fast. I don't really think it's too bad, but better build-up would be nice. It's more exciting to see a full combo form than a slight change. SaGohZa should be interesting though.
So all in all, I still like OOO, but the cheetah powers need BETTER EFFECTS!!!!!!
By the way, Mezool's actress is only 13.
