Kendo part. You pretty much know how bad it is if you know what you are watching.
Its like watching a golf anime and the animator doesn't know how to play Golf.
I don't have problem with the girls etc, they are nice. Watching the girls do tsuburi in the OP however, make me RAGE... god, if they want to do Kendo anime they can either do it right or make it freaking super power up far away from the truth.
