Having found all the titles I set out to read all 6 issues.
So far it's got everything: zombies, ghosts, were-beasts, mummies, vampires etc...and its pretty entertaining. It's not dark and dreary (this probably has a lot to do with the art) and needlessly depressing. The protagonists spend as much time as possible trying to live as quietly as possible while fulfilling their abnormal needs.
Like Wally said, it's not depressing. The art chores are done by Mike Allred, so imagine that popart style applied to vamps, weres and zombies. Fun, n'est ce pas?
