That's the thing, though--it's neither new nor (to me) particularly interesting. Babylon 5 did it (albeit with a scifi twist), Hellraiser (John Constantine) did it and other comics have at least touched on it, and Philip Pullman did...some truly original (in the sense of truly crap storytelling) stuff with a similar theme.

I dunno. I'm not against the sympathetic-Lucifer angle, because that could go in some very interesting ways. But making good as bad as bad pisses me off, especially on a horror show that usually knows better.
