Just finished the Resurrection Man trade. It's definitely an interesting concept to have a hero that comes back to life with a new power every time he dies. However, I can't say I think they executed it as well as they could. Mitch dies too often. It'd be nice if the books took more time exploring his newest power, and seeing him use them for more than a few pages before being offed by someone.
I also think the whole heave/hell, precious soul stuff is a tad bit cliche. The storyline might have benefited if it focused more on his amnesia, search for answers, and dealing with his various powers without throwing that in there. Kinda sad this got cancelled. It really could have gone somewhere great.
