Home invasions are a staple of horror, and while it offers a largely paint-by-numbers approach, Trespassers delivers a passable, if familiar addition to the subgenre. It hits all the markers: dysfunctional couples, a remote setting, questionable decision making; drugs, booze, and assholery abound. There are major logical jumps and a few narratively convenient oversights, but mean-spirited carnage and strong female protagonists make it a compelling watch.
