Ah, one of the few good english dubbed anime.
Basically, in 2001, Japan made a horror anime series starring a bunch of... high schoolers (?). It sucked and ripped off horror films. So when it came to america, ADV made it into a parody anime, rewriting (more like destroying) the entire script. Now its anime with pop culture reference, crude humor, and 4th wall smashing.
Its AWESOME. Funny, clever, and a totally endearing. While the first 2 episodes are quite lame, after that, they are all good (save MAYBE 1 or 2 episodes here and there). The characters are great, the music is great (stolen from Inuyasha, I swear), and the games are grand.
