Can you tell me what it is about it that's got you hooked?

Hmm. A couple of things. The premise itself is interesting, and the execution of the premise is done in such a way that makes the characters involved feel real and human. I like the maturity of the series, with adult decisions and complications in the forefront. I also identify with Johnny's social difficulties, though his are externally enforced. The writing is intelligent and often inventive. All it needs now is a revved up fandom. :-)
