Once upon a time… horror films knew how to consistently land their third act. The original Black Christmas, The Exorcist and John Carpenter’s The Thing build tension and escalate the scares without falling apart by the end, but you don’t even need to go back that far to find ones that get it right thanks to (relatively) recent movies like [REC], The Mist and The Innkeepers. But more than any other genre a lot of horror films from the last few years simply drop the ball before the credits roll. Andrés Muschietti‘s Mama continues that trend unfortunately, but truth be told its grip is pretty damn tenuous from the beginning. After Victoria and Lily’s father kills their mother and some co-workers he takes the girls on a drive that ends with a crash in the woods. The trio wander the cold, desolate forest before finding an old, seemingly deserted cabin and settling in for the night. Father of the year doesn’t make it to morning. Five years later the now feral girls are found and returned to their uncle Lucas (Nikolaj Coster-Waldau) and his girlfriend Annabelle (Jessica Chastain), but something else has come home with them and it’s not too keen on sharing custody.
