That voice belongs to Abbie (Gugu Mbatha-Raw), speaking to us from beyond the grave. As things kick into motion, she takes us back to her terminal cancer diagnosis and her subsequent decision to do everything in her power to set her fiancé Sam (Michiel Huisman) up with the perfect woman to take care of him when she’s gone.
On paper, the impulse is understandable -- a similar story went viral in The New York Times last year. But in execution, the plan is a horror show. Abbie basically auditions women to see if they’re "good enough" for Sam, deeming some too high-strung, others too weird. The series of value judgments aren’t funny or sympathetic, but characteristic of the regressive, clunky humor that’s consistent through the entire movie. Gluten-free people are psychos! Women who love cats are weirdos! The list goes on. That Irreplaceable You doesn’t completely fall apart is solely due to the unbelievably good cast: Mbatha-Raw and Huisman (who are, to be fair, perfectly charming) are joined by Christopher Walken, Steve Coogan, Timothy Simons, Brian Tyree Henry, and Kate McKinnon, all stuck in roles that completely waste their talents.
