Planet of Vampires was my favorite Atlas book (along with Morlock 2001) and unfortunately both of them had "cliffhanger" endings to what became their final issues. Even if the new Atlas "reboots" those series, I would get such a kick out of seeing those cliffhangers resolved somehow. Even if it was done as a special out-of-continuity special issue, or a mail in premium, or something!!
When I was in my teens I remember taking it upon myself to try drawing a "Morlock 2001" issue #4, picking up where the cliffhanger left off... but I don't think I ever got very far with the project.
