Medaka Box
Personally speaking I thought this was beyond boring, but I was prejudiced against it before I started watching it so I don't think that should put off anyone who's actually interested in watching it. The direction and animation are shounen by numbers; if this wasn't animated by what's-left-of-Gainax I wouldn't have given it a second glance, as I dislike Nisioisin's writing anyway.
What I really don't like is the overbearing background music that played throughout the vast majority of the first half of the episode. Sometimes I think this kind of thing almost works - .hack//Sign would have been terminally dull without blaring Kajiura music over the top of everything - but here it felt like the director had looked at the first episode of Utena, asked the composer to write something that sounds like the main theme for Ohtori Academy (I don't know the name of the piece of music. but you'd know what I meant if you watched Medaka Box), and just made that play on loop for about ten minutes.
Also, why does Medaka have to have impractically huge tits? I know, it's anime, but still, she should be on the floor with those things.
