The script's okay. They've paired it down a lot from the novel, but it retains the flavour quite well, and the first few books were actually quite enjoyable. They've perhaps paired it down a bit too much, since some of the sequences are hard to follow, but that might also be the artwork, and even with the chopping that's been done, Volume 1 of the comic book doesn't contain all of Guilty Pleasures, the novel - it just stops part-way through. And not particularly at the end of an arc, either. It just stops. Bad.
The artwork's the biggest problem, though. Brett Booth isn't up to the job. It's very reminiscent of Silvestri in things like The Darkness, in that there's pretty much The Male Character and The Female Character. By that I mean, all the women have identical faces, and so do all the men. you distinguish between them by hair colour, hair style, and clothing. There are a few places where proportion is completely blown (typical human proportions mean the hips-to-feet and hips-to-crown distances are about the same, but sometimes, Booth makes the legs more than twice the length. Why, yes, these are female characters I'm talking about. How did you guess?). Plus, there are Comic Posture panels, where no-one's going to stand like that.
Not only that, but Booth's artwork doesn't work sufficiently well to tell the story; he (or she) can't convey emotion well enough, and given that the prose that used to do this is now replaced with art, that's a problem.
I can't see these surviving too long. They might survive better as the collaboration improves, but sooner or later they're going to slam straight into Hamilton's switch from procedural into furry porn, and I can't see those selling well in America.
