I picked up Issue #0 for free my last few minutes of Comic Con and read it while homeless. I like it a little less than the one issue of the Dark Tower comics I read, but really, one issue isn't much to judge it by.
So instead let me make a general observation.
Hitchcock said he would never adapt The Brothers Karamazov to film because it was already perfect in the form it was. Instead he adapts a nothing book into Vertigo. In film form, it becomes the greatest of all time.
It's for this reason that I don't understand the recent explosion of book-into-comics adaptations. If you love the book, why not just read the book? When I read something like The Talisman, all I can think is, "Is this good enough to read the original?" If not, it's not good enough to read the adaptation either.
