Wow, I went in not expecting much and it still sucked
The movie starts out interesting enough; a narrator from 2012 explains that most of the world's population is dead. Not from disease, global warming, or war like most expected, but running out of gasoline as a resource.
Unfortunately, after that, the interest is gone. It does little more to explain what lead to the disaster, other than people started living in Anarchy and chaos.
So, going from there, we meet the narrator and his small "family" of refugees who live in an abandoned hospital. When they find and take in a newcomer into their home, they learn of the Rovers, a group of cannibals who kill and eat other survivors.
This movie offers nothing in the way of horror, and the ending is so atrocious that it's not even funny. The dark scenery, awful acting, predictable storyline, and hilariously bad lines make this movie nearly unwatchable.
But if you do go see it, expect to see the worst apocalypse-based movie you've ever seen. Enjoy!
