I disagree whole-heartedly: Marvel Zombies is some of my favorite zombie material from recent memory.
it started off rather well, and were actually rather frightening to think of-- Zombies with superpowers? nobody would be able to stand up to that!
But as it went on it just got more weirder...espeically the ending.
the zombies eating that galactic dude and then somehow gaining the ability to become space zombies, and travel to other planets. seriously, it just seemed to trail off there and it was one of those "the reader makes up what happens next here" endings.
I just don't like it when stories like that has no real ending.
In that case, you just read the first issue.
Might as well inform you that the story actually continues.
Basically the space zombies (heh... funny concept) fly around the entire galaxy, eating everything in it. No life is spared anywhere. After that they decide to head back to earth to try and repair that dimension travel device so that they could jump to another universe and start all over. Anyways the few humans that survived by staying on that asteroids have established a semi primitive colony on earth where they're trying to repopulate earth. That's not going so well seeing as they're faced with several problems like "not enough survivors to prevent inbreeding" and "one of their kids is a douche who's trying to take over the leadership of the colony". Then there's a big showdown between the zombies and the survivors which gets resolved in a really weird way.
The story continues after that in issue 3 but I don't know how that goes.
There was also a prequel that explains how the heroes tried to stop the zombie infection from spreading among themselves and how that ultimately failed.
They also did a story where the black panther and storm get transported to the Skrull planet as it's being eaten by those space zombies (please don't ask me how and why. sigh... it was a magic frog statue.).
Then there's a different comic story where Ash from Army of darkness ends up on the Zombie Marvel world just before the superheroes changed. It was called Marvel Zombies vs Army of Darkness. It was actually a bit funny.
