The words "Worthless" and "Hilarous" come to mind when I watched this. I only even attempted to watch this because I found the idea of an anime based solely around a girl "Jazzercising" to be undeniably funny. It did suprise me a little bit with what seemed like an attempt at a story-line. But soon after that the show got to the real business at hand: Boobs. A whole 4 handfuls of 'em. The only thing that gets a workout from watching this show are your eyes from the constant motion of her boobs. It was funny for a little bit, and then it was repetitive, and then I stopped caring. They tried to keep it interesting by having her change outfits but that didn't really help by the end.
The story gets a 1 because it was far-fetched and stupid.
The animation gets a 9 because it was actually very very good. Despite how it was being used.
The sound gets a 2 because there was some level of talent required to voice an annoying anime-girl with a high-pitched whiny voice.
Characters gets a 1 because there was 1 character. And she wasn't a good one. Unless you count her boobs, which makes 3 characters. And if you go that route the boobs were really the ones with the character depth.
So overall my awesome math tells me it averages out to a 3/10.
It was worth a few laughs at first, but then it get's repetitive, and then it's just stupid.
Time I cannot get back, watch just about anything else, unless you're looking for a cheap PG masturbatory aid.
