We're going back to Buffy's roots, save one little snag... the breaking of the fourth wall! Sort-of. Then again, having the book of Vampyrs get all erased and then start to redefine the magic of the whole world just means that nothing is sacred and rulebound. Then again, that's kinda what I love about the series. It eventually manages to redefine itself repeatedly, only to smash it to pieces once more. I don't know of any other series that has the courage to do this so regularly with a cast of misfits so well loved by so many ubergeeks.
