Ready-made fanbase of deluded morbidly-obese college girls? Rambling screeds about the beautiful purity of homosexual incestual relationships? What, you mean this show wasn't an anime before?
Don't forget slashfic hags who feel the need to screech that anyone who doesn't think that two male characters are involved in a incestual/homosexual relationship simply because they appear in scenes together is a bigot.
This is one of those things that is expected yet shocking at the same time. Hopefully Japan starts making hilarious animated versions of all American slash shows.
Having never actually seen the TV show, I'm kinda curious now if only because of the studio. Madhouse is responsible for animating a lot of shows and movies, including some really great stuff (Kaiba, Black Lagoon, Boogiepop Phantom, Metropolis, all of Satoshi Kon's films).
