So did Boom! cancel,Cataclysm, did the writers quit or did the license go away? Something obviously happened. This issue jumps three years ahead of the previous one, then another five years from where it opens.
Bechko and Hardman follow Professor Milo (from the second movie) so they can avoid having to have Charlton Heston appear. He gets a mention, but then they focus the issue on what was going on with the spaceship during the second movie. To explain the third, in other words.
It seems like the natural last issue for the series, but they seem to have jumped ahead quite a bit. Cast members from Cataclysm sort of pop in for cameos, but it’s much more a movie tie-in. It’s trying to logically explain what Heston only agreeing to second sequel if the world ended broke.
It’s well-written enough, but it’s a terrible last issue.
