It is fantastic and I can’t recommend it enough. Like you say, the zombie genre is often fundamentally misanthropic, and apart from how much schlocky B-movie fun you can have with zombies as a plot device (and it does have a lot of fun with how much weird and silly stuff it can get away with) the stereotypical misanthropy of the genre almost makes it all the more ideal for a story that wants to interrogate and criticize antisocial escapism, power fantasies, hedonism, etc and offer a healthier and more positive position instead.

It’s a meaningful work of art disguised as a schlocky satirical B-movie sort of thing and it’s just great.
