I'm not really sure what in this quest really has to do with Land of the Dead, other than there being a bunch of rich people in a tower somewhere. Unless you mean to compare the ghouls to John Leguizamo's character? In which case, I'm not sure who to be more offended for: Leguizamo or the ghouls. I'm wracking my brain, and I can't think of a single other comparison. I think you're stretching it.

Also, there were no extraneous lesbians devoured by zombies in this quest, so your analogy immediately fails.
