More or less... I mean "alien invasion" is equally implausible but it is a manifestation of a real fear of invasion. So from that angle "zombie" apocalypse is somewhat plausible in that there is a real fear of a "mindless horde" e.g. a mob dumbed-down by reality TV elects a reality TV star to be commmander-in-chief of a nuclear arsenal. It's not that far-fetched.
At least the pandemic or comet collision are somewhat plausible.
