This film does a terrific job at eliminating audience members - weeding out the weak. Do not watch this film if you can't handle: gratuitous gore of the intestine eating sort, explicit gay sex (between zombies using fresh improvised gashes as sexual orifices), frequent cross-cutting of "reality" and "film", and dedicating major segments of the film to an art house indie director criticizing art house and non-mainstream film.
But if you're a weirdo like me and think all of that sounds like a hella good time, you will or will not be disappointed ;)
Some things that are truly outstanding here: the director character's lover is constantly encapsulated in a bubble of silent film; the lengths to which this director goes to be "avant garde" and the heights to which those attempts accidentally succeed and the hilarious depths to which they intentionally fail. Otto, the main zombie character, is constantly battling for a sense of identity, and his story juxtaposed and interweaving with this director's vision (Up With Dead People is the title of her film) makes the titling very apt (which the title itself is a wink-wink nudge-nudge satirical jab at fringe cinema).
Ultimately, this is not so much a film about zombies as it is a film about film; the zombie aspect is merely used as fuel for probing the subject of identity in both the personal and social arena.
Hot Gay Sex notes: for those looking to avoid poorly done zombie sex and see hardcore human/human (in appearance) gay male sex in the context of narrative feature, around 1:20:00 is the best example; beyond that you're on your own and in for some zombie/zombie, zombie/human combos
