Hanamaru Kindergarten is...okay. It's not really something I would really recommend, but if you've already started, might as well finish it. Art style is okay, I don't know how I feel about it, though. I might rewatch it to check them. Characters are pretty cliche for anime, albiet being set in a kindergarten. I personally really like this. I'm a sucker for anime with no complicated story with plot twists. This is just what it is, a kindergarten comedy.
