If this movie had stuck with its black comedy premise all the way to the end it might have been a memorable film, as. e.g., the later "War of the Roses." As it is there is some marvellously funny dialogue in the first 2/3 of the movie, as well as some hilarious slapstick in the hotel room when Allie's and Pullman's characters are deciding how to deal with the corpse. The portrayal of the husband's all-doctor family is pretty good, too. Unfortunately all of this is wasted in pursuit of the prized Happy Ending, wherein Marjorie's infidelities are seen as a stepping stone to a fuller relationship with her chastened husband. Puh-leez.
