Rokudo no Onna-tachi (Rokudo's Bad Girls) anime probably not going to do the (great) manga any justice but I'm surprised it got adapted at all. Source manga is about seven years old. Truly wacky shonen manga where the hero becomes irresistible to delinquent girls and becomes a weird kind of "patriarch" in high school delinquent wars.
One informal and unscientific test of anime production values is the Cheap Ending Animation Test, and this one loops a four-frame animation for a solid minute. I don't even know where that falls on the scale.
Here's my buddy Ogiue Maniax talking about it, probably the only English-speaking blogger to ever bring it up.
This is another one where I've hit the third episode, and despite the anime adaptation being a slide-show... oh, right, Rokudo was an excellent shonen manga.
I said our hero becomes a "patriarch" because that's how I can best describe what happens. Rokudo can't fight like his girls can fight. He shows up terrified and he gets the shit beat out of him every time. It's his extreme resolve to be kind and do the right thing-- despite, again, absolutely getting torn a new asshole every time-- that makes him an inspiration to his pals. I really like this kind of hero.
