This movie is on par with its zero-brainer title.
Though it starts off with a decent idea; a different vision of zombies that don't eat people, etc. Zombies taking up a place in society - this could be read (this isn't a spoiler) like the people who work 80 hours a week in terrible working conditions just to get a job more than the next poor schlub, etc. This idea quickly falls out next to the cheapest "humor", bad dialogue and an apparent inability to build up plot and have some actual story telling.
The movie looks like it is partially Robot Chicken style inserts, within a mediocre plotline, and well... yea, it doesn't really come out like something you are interested in watching. They added cheap slapstick style gags and "bellow the belt, haha this is funny because it is making fun of political correctness" at every turn, either hoping it would cover up for the b-series acting, the dull set up, the... well, I suppose everything.
I really can't imagine anyone that isn't stuck in an "antisocial teenager" phase finding this movie either funny or entertaining - maybe that's the target audience? If it wasn't enough, the people who worked on the colors and lighting must have taken a bunch of b-series horror films as an example - everything is shot in the dark, unengaging, almost can't see sh** half the time. Yea, shooting in the dark may work sometimes, but not when you have no atmosphere, dull scenes, cheap comedy and less than desirable acting.
As a note though, for any writers out there, this movie is a great example of why "show don't tell" is a thing. Because you can't see sh**, but they sure do spell out EVERY plot element and detail for you.
The basic ideas in this movie deserve a rip off, but this film deserves to be forgotten.
