Todd Willcox’s review published on Letterboxd :
THE CRAZIES deals with a terrifying idea -- a small Iowa town has its water supply contaminated. How is unimportant. What IS important is that the contamination creates maniacal, killer crazies. All of them are out to kill anyone that they come across. The crazies are trying to be stopped by a sheriff played by Timothy Olyphant and, rather reluctantly, his wife Radha Mitchell. Both Olyphant and Mitchell's performances help the film along as does the film's special effects. It's one I like well enough to have in my permanent film library, but it's no horror classic by any means.
