Absolute waste of time. No story, no plot. Did I mention there is no story? Also, nothing that happens in the movie is believable. Unless a dude single-handedly fighting an entire zombie army on his lonesome with essentially his bare hands, while making stupid decisions and not being logical is something you'd consider to be a story.
Somehow dude doesn't ever get bitten, despite the fact that these acrobatic zombies can jump, climb ladders, and magically get on top of things. -- like speeding cars. Except when they can't. They are very quick on their feet, as they can almost out-run a truck, and while they feel the need to try to rip said dude apart, they don't want to eat him. Whut?
The daughter fared better. She was able to out-run the zombie horde a couple of times, even without food or water. And though she had no real wilderness experience, she managed to find her way clear to the top of a mountain where she lit a fire for a smoke signal. Because, even though they weren't expecting the zombie apocalypse and she'd just left the camper presumably to use the toilet, she happened to have matches on her while she was sleeping. Presumably in the coat she lost along the way. Can you say plot holes?
Here's another plot hole -- when dude tries to call his daughter on her cell phone, it rings in the camper. So he has two working cell phones, and obviously is getting a signal or the daughter's phone wouldn't have rung... but at no point does he try to use one to call his wife or 911, or anyone at all for help. Instead, he fiddles pointlessly with a HAM radio.
The film doesn't bother explaining where the zombies came from, what happened to the wife, or how they're going to get down the mountain to safety (is it even safe back in civilization?) without a vehicle, food, water, or a story line.
Save yourself the aggravation and watch something else.
