A delectable premise finds maniacal delivery in Drop, a taut new thriller from Happy Death Day’s Christopher Landon. As penned by Jillian Jacobs and Chris Roach, the film boasts the sort of idea so ripe for mining that it’s perplexing to think nobody has done so before. An AirDrop thriller for the iPhone era. Drop was, in fact, conceived only when the girlfriend of its executive producer, Sam Lerner, began receiving dodgy Shrek memes one night in a packed restaurant. It’s no huge leap to climb from crass to creepy and then on to criminal. In Landon’s hands, it’s splendidly scaled.
