The story of a loner, daydreaming, unambitious student who is dragged into the ultra-glamourous world of competitive cycling.
What's good about it?
Some nice supporting characters. An original starting point (Bicycle anime!). Lots of drama and suspense. Not unfunny at times.
What's bad about it?
I hate the main character Shinozaki. He's weak, weird and awkward. He says uncool stuff all the time(I want to ride my bicycle with everyone because everyone is great and I love riding my bicycle with everyone. Totally unappealing. Besides that, the pacing is slow after the race starts, the dialogue is lame when they talk serious and after the novelty of cycling wears off, you're left with the reason you never got into cycling in the first place, it's hella-boring.
Overdrive never seems to be able to blend comedy and drama effectively, so much so that the jokes sometimes come off as inappropriate for the moment and the attemps at seriousness are just that, attempts. At the end of the day, this series is mundane sports anime that is unique only in it's choice of sports. There's better choices out there.
