Did You Know?


In the airport scene, a businessman mentions that his "pool cleaner has gone rogue". This is an in-joke about one of the supernatural events in Paranormal Activity 2 (2010), which was also directed by Tod Williams. See more »


The main characters run into a kid sitting on a swing petting a dog. They finally get his attention, and it turns out he's infected and he starts running towards them. They shoot him. They then see dozens of other infected people behind trees and starting to chase them. They run and hide under a boat until the infected go away. The problem is there's no way they would have time to hide under the boat with the infected not seeing them. The infected people chasing them were a mere 20-30 feet away. See more »

Absolute garbage. Possible contestant for worst movie ever.
1 August 2016 | by callumhuscroftSee all my reviews

I'm not talking about it being just a bad adaptation either, the book wasn't exactly King's best work, it was just his jab at a zombie story. However, even a King book that isn't great by his standards is still a good book. He always writes a good narrative and he always has some good and fleshed out characters that grow on you throughout the story.

The characters in this movie aren't fleshed out, and they don't grow on you at all. The book was heavily driven by dialogue and through the viewpoint of Clay, the protagonist. There was very little in the way of good dialogue in this movie, there was practically nothing in the way of character development.

The plot moved way too quickly to be good, as if they were just checking a list of locations from a list. As a result, the plot felt like a convoluted nightmare where it was impossible to care. I won't spoil the ending but if you watch it, just know it's perfectly normal to feel angry.

The movie also had a level of technical ineptitude I thought impossible, with shitty CGI and worse sound effects.

I could write for hours and hours about how bad this movie is, but that would be a bigger wall of text than I've written already. Watch at your own risk, but if you want an enjoyable apocalypse story just read the book instead.

If you're gonna watch, get a few shots of vodka down you first.
