Barbarian (2022)

It is a dark and rainy night and Tess Marshall (Georgina Campbell) arrives at a house outside of Detroit that she has booked online.  Though her code works on the lockbox, there is no key.  Her calls to the rental company are not answered.  Pounding angrily on the door, she is about to leave when the lights turn on.  Keith (Bill Skarsgard) opens the door.  He states that he rented the house and shows his reservation from a different website.  Though Keith offers to share the house, Tess isn't about to stay with some stranger.  She is forced to reconsider when she discovers that hotels are booked solid on account of a convention.  Keith offers her the bedroom and points out that it has a lock.  Though she is awoken in the night by someone creeping around, the night is otherwise uneventful.  In the morning, Keith has already left and she sets out for her interview.  Returning to the house, she finds there is no toilet paper and heads down to the basement.  The door swings closed and she's locked in.  Then she finds a secret room that looks like a torture dungeon.  Then it gets really weird.

Meanwhile in California, AJ Gilbride (Justin Long) is driving down PCH when he gets a call that sends his life into a tailspin.  His acting career may have just come to an end and his finances are unlikely to survive the year with his current level of spending.  As luck would have it, he owns some property in Detroit.  He flies to Michigan, gets a key from the rental company, and heads to his house.  Looking at the neighborhood, every other house is in ruins.  Two cars are parked out front.  Inside, there is still luggage.  His interest in the house is how much he can get by selling it.  As such, when he stumbles upon the secret room, he starts measuring the added square footage.

In an extended flashback that shows the fairly nice neighborhood in the early 1980s, Frank (Richard Brake) is shown leaving the house and stalking an unsuspecting woman.  The events of today are a result of the extensive crimes of Frank.

A surprisingly good, entertaining, and frequently humorous horror film.  Good popcorn fun and definitely recommended.
