So, I've been wanting to watch this show since god-knows-when, but kept forgetting about it. This being a SHAFT show, I considered it mandatory for me to watch it, so I breezed through all three seasons and the specials and all I can say is that this show is awesome! All the girls are seriously dysfunctional (except Nami, who is just normal), and Kafuka is the biggest troll of them all (which makes her my personal favorite). I don't think any other teacher than Nozomu could handle such a class of misfits. They'd either be dead at the hands of Chiri, or have run away to escape the madness.
I too would have liked the BDs to have been subbed, but with the huge amount of work the various fansubbers put in the TV releases, I think we're lucky the show got subbed at all.
I'll probably rewatch everything later, to catch details I missed earleir, but at lkeast I know I'll be thoroughly entertained if I do.
