The Crazies (2010)

The Crazies is a tense, well-executed remake of George A. Romero's 1973 film. Set in a small town where a water supply contamination turns the residents into violent, homicidal maniacs, the film follows a sheriff trying to protect his wife and escape. It is a grounded, realistic take on the 'infected' subgenre, focusing on the chaos of a small town under military quarantine.

With strong performances and a relentless pace, it is a highly effective horror-thriller that manages to be both scary and thought-provoking. It is a great example of a remake done right.
