Not the guy you're talking about but I wasn't overally impressed by episode one. Well... actually that's not true. The twist with Chiko intrigued me but I thought the rest was kind of "meh." But I'm often wrong about first impressions and now this is one of my favorite shows this season.
To the person who only watched 3 episodes, things are going to change from now on so I'd at least watch up to next episode. This could very well change as drastically as Gurren Lagann after episode 8.
