I picked up the first trade of Outcast, but I didn't enjoy it. I just didn't find it engaging, which was really disappointing.

One element of the story is that the main character's blood hurts people who are possessed and draws out demons. Kirkman's go-to method of keeping this in play is to have as many people as possible smack the protagonist in the nose hard enough for him to start bleeding everywhere. I think there were 3 nosebleeds in 6 issues. Not a huge criticism or anything, just something that made me laugh more than I should have.
