Is it possible to write a review without any ass puns? Butt of course! (D'Oh!)
Story:
This is a sports shounen anime like every other...BUTT with an all female cast. And not only that, it is full of fanservice, tons of it. Now the question is, is that all Keijo has to offer? Surprisingly not. The girls take this sport seriously, like they would do any other sport. Keijo never tries to cover up the fact, that it wants you to drool over the well-developed teenage girl bodies, but it also tries to make itself a serious sports story. On top of that, we have insane power moves straight out of an over the top shounen, which (thanks to the nature of this anime) are the most hilarious thing about Keijo. I'd say the story works as well as you allow it to.
8/10
Art:
The fights (or as they call it, races) are full of energy and quite spectacular to watch. However, there are some noticeable animation flaws, which I personally don't mind very much, butt I know that many people have major issues with these. The character design is okay, the girls could look a bit more distinct, especially since they are mostly running around in uniform swimsuits.
5/10
Sound:
The opening song is awesome. The ending isn't quite as good, but still solid. Voice acting was good in general, though nobody was really able to do a standout performance (and I'm saying this as a fan of Rie Takahashi).
7/10
Characters:
There are a lot of cute and/or badass girls in Keijo that you should have no hard time choosing your favourite. The cast as a whole is good enough to work, though I feel like this would've worked even better with more unique characters. I'll exclude Nozomi from this though. She is your standard shounen main character, but female and willing to show off her body. Which leads me to another slight criticism I have: they don't seem to mind showing a stadium of thousands their titties if it means victory. That felt a little awkward (yes, I understand that this is an ecchi anime).
7/10
Enjoyment:
All criticism aside, Keijo was an insane amount of fun to watch. I enjoyed the fanservice, I was rooting for my favourite girls to win and I laughed my ass off (hehe, ass) at all the over the topness. Keijo is the epitome of what some consider "brainless fun". This anime does not try to be the next Evangelion or Madoka or whatever, it wants to provide entertainment and goddammit, does it succeed. Absolute recommendation for everybody (unless you think female bodies are sexist, in which case you can go die for all I care).
