I've watched my fair share of sports anime, especially recently where I've been on a girls sports anime kick, and I have to tell you Cinderella Nine is possibly the most boring one I've watched so far. Story: Cliche as hell. Cliche is expected in sports anime but holy crap is this anime just by-the-numbers all the way through. The only "interesting" part is that the club isn't a club until Episode 8, before that is is an "association". Additionally the way the team is formed is, for the most part, hilariously terrible. Characters are introduced and join sometimes in the same scene, while characters likeNakano join because reasons.

Art: Holy crap is the art medicore, or even bad. Characters barely move outside them playing baseball (Asada spraying the team with the hose is a prime example of this), the lip syncing is not very good at points (Iwaki especially), goofy faces are a main stay, and I've even noticed a colour inconistancy as early as episode 2 (Suzuki's blue glove turns tan when Ukita takes over playing catch). It seems like there was little in terms of quality control and the characters' faces always look wonky. There's also a fair few scenes that are static scenario with the characters' faces flashing over it as a form of "reaction". It's really bad.

Sound: The OP is decent, and some of the music plays turning big emotional scenes is passable but over all not great. Nakano's voice drives me up a wall.

Characters: There are a lot of characters and nearly all of them get no meaningful screen time or development. The only decent character in my opinion is Kurashiki since she has a decent character design and a more interesting back story. Nakano is the worst, with her nyan speech pattern making her unbearable. Asada is fine I guess, if not very bland. Iwaki and Ukita are annoying. Suzuki has some interesting aspects to her in episode 2 but afterwards has the personality of wet paper. Arihara has the personality of a main protag but without the screen time or growth or interesting back story, and her friend Kawakita grows in episode 7 but otherwise is like a cinderblock. Nozaki has dumb hair but is fine, and Tsukumo is fine. Other characters are kind of just there. The teacher character is the generic supportive teacher archetype so eh.

Enjoyment: What a slog. Every episode felt like they were 60 minutes, rather than 24 minutes. I was able to easy binge other terrible shows like Hanebado! because at least they weren't boring. Hanebado! may have been a melodramatic pile of garbage but it was at least a melodramatic pile of garbage and not a boring pile of garbage.

Overall: Would not recommend to anyone. Cute girls doing cute things? The girls aren't that cute due to derp faces and weak character designs. Sports? baseball is a fairly boring sport in my opinion, and the anime doesn't even really go into that much detail.

3/10 bad anime is bad
