I have finished all The Deadpool Killogly books but read Killistrated and Deadpool Kills Deadpool out of order. It didn't make to much of a difference but there was a few things where I went, "Oh that's what they were talking about in the other book." I think my favorite was the first one I read Deadpool Kills The Marvel Universe.
I am just opening Deadpool Vs Carnage. I know it's not part of the Killogy but when I thought of these two together I had to read it. Also I didn't what to start yet another Deadpool thread or I would be starting one all the time.
It was an interesting read to say the least. 2 unkillable dudes trying to kill each other while 1 upping each other in the crazy department. I do feel the book was made for a low age rating because words were beeped out and not as much gore as I would have expected for this kind of fight.
