Hibiki is quite cool and refreshing. Todoroki rockin out is what I look forward to every episode.
EDIT: I just realized it sounded like I was advertising for a new water company. Hibiki! Fresh Spring Water!
I know I'm spoiled with newer stuff but Kuuga's monster designs and effects are total crap. Mind you I've only seen episode 1. I like how he henshins though,the idea of just fighting and it appears is cool.
