Crawl (2019)
There’s nothing mutated or supernatural about this one. But Crawl—about a young woman and her father trapped in his Florida home during a hurricane, a situation made infinitely worse by the fact that floodwaters bring in dozens of furious alligators—has the kind of “this could actually happen in some nightmare version of real life” creepiness you’d expect from director Alexandre Aja, who also made High Tension, Piranha 3D, and The Hills Have Eyes remake.
