Honestly, I think it could have been a cool concept if they had maybe done 10 pages in pitch black. Then, in the subsequent pages, just let Guedes go off and draw the craziest things he could imagine. That would have been awesome. Guedes art + prestige format is honestly worth more than $4, so if half of the issue lacked art, I think I would have been okay with it.
I think the major problem with this issue, however, is that the whole Book of the Dead arc seems really pointless and dumb. One issue was dedicated to set-up; getting Ray ready to venture into the deadside. Literally nothing happened in the second issue, and then there's only one more issue after that. I have to say, I'm not happy with this weird and dumb turn that Salvation has took, and I'm considering dropping the series if it doesn't pick back up with the 4001 arc.
