It was a great book. Though I wish he would've spent more time 'fleshing out' the new gods for I found them very fascinating.
Also, read the Preacher graphic novels! If you haven't read it already, you'll love it - and they're coming out with a Preacher movie so you might as well get the story before Hollywood rapes it (though they might not - last I heard, Ennis was actually doing the screen-play). Also, any of the Azarello or Ennis Hellblazers are good choices. I hope I'm not preaching to the choir here...
And, I don't know about you, but I'm a huge Starlin fan - especially any comics with Thanos in them.
