It was hard for me to start enjoying this series. I mean, like really enjoy it. I couldn't get over the fact that as well drawn as their faces are, the hands look wacky, the animation choppy and unfluid, etc... But I kind of grew fonder of its style, its characters and its jokes. Of course, I'd love an improvement in those aspects, but the key of the series is its dialogues, and that can still be appreciated as it is.
The fact that you went over the fake band thing again is a really nice touch and fueled the jokes well.
