It would serve its audience better if it paid more attention to a stronger structure and a believable plot, but its flaws don’t keep it from being affecting for those who like their love stories on the lachrymose side.
The dialogue creates an arch and artificial mood, never sounding like real talk despite the clearly talented actors (Gugu Mbatha-Raw and Michiel Huisman) playing the roles. The film itself seems to be in denial about its own story.
Wohl never manages to achieve the proper tonal blend. The result is neither sufficiently funny nor moving, lacking the truly daring humor that might have made the film a bracing dark comedy. It's a shame, considering the estimable ensemble.
Gugu Mbatha-Raw is a charming actress who radiates poise and intelligence, which is why Irreplaceable You — in which her character acts in ways that are clearly self-destructive and counterproductive — rings so false.
