Issue #2's out, and all McFarlane talks about in the blurb near the back is how the 1st issue sold out and how they had to rush to get more printed, blah, blah, blah. I was trying to put my thumb on why this book was bad. There are all of the things that are mentioned here, but I think in general, it's that their trying to tell what could have been a decent story with completely gimped art direction. Had the art direction and character art concepts been abandoned for something more original, I dunno, this would be middling-to-good on my nerdom scale.
The writing is not terrible. Possession as a character mechanic is cool, and they could have gone in a lot of different directions with it. Ditto the secret paranormal-paramilitary org the dead brother belongs to. Ditto the priest angle. But it's like they all sat down and went "How can we make another Spawn? Kids these days have short attention spans, perhaps we don't have to think that hard about this after all..."
