"Knock at the Cabin" is another effective horror thriller from M. Night Shyamalan, balancing suspense and terror before an ending that over-explains it all.

With "Sick," screenwriter Kevin Williamson and director John Hyams use the pandemic setting to create a tense, smart and relentless thriller.

"Halloween Ends" is a messy end to Michael Myers, and its plot choices may anger fans. But when it embraces its slasher identity, it's a bit of dark fun.
