I found Ao no Kanata no Four Rhythm strangely intriguing as I watched everything unfold. It really turned into a sports anime of sorts as all the action focused around their sport of choice FC or Flying Circus. Flying circus is about people dog fighting with these special gravity shoes that allow people to fly around at high speeds. I think people will like the anime due to peoples fascination with flying around. And these people can surely zip around. Even tho it does take a second to get rolling into the main action. I found myself enjoying it. Give it a chance and itmight grow on you. Can't help, but root for the flying fish.
