My friend has a copy of the first issue, and i looked through it and liked the artwork a lot. Once all five issues are out i'll ask if i can borrow them, and then i will get my thoughts back to you on that.
But you should seriously read Dan Dare, it's amazing!
To be honest, I never picked it up because of my complete boredom with all of the public domain character books coming out. None are any good and none have interested me beyond the first issue of The Twelve and that was a letdown. I don't blind buy Ennis. He just hasn't proven to me that he's worth it. I do like him, though.
You don't really think The Demon is better than Preacher do you?
