Peter Ericson’s review published on Letterboxd :
While the film is never boring, there are better ways to spend 103 minutes than watching "Did You Hear About the Morgans?" Writer/director Marc Lawrence’s formulaic and predictable story results in the proceedings being only sporadically engaging. None of the characters come across as three-dimensional human beings, which makes it nigh impossible for the viewer to care about them. The movie qualifies as passable entertainment, but it is quickly forgotten once the end credits have rolled.
The humor is derived largely from fish-out-of-water situations as Paul (Hugh Grant) and Meryl (Sarah Jessica Parker, "State and Main") Morgan are forced to relocate from New York City to a small town in Wyoming after witnessing a murder. All of the jokes are clichéd to some extent, but "Did You Hear About the Morgans?" contains a few—too few—genuinely funny moments. The amusing opening sequence—messages left by Paul on Meryl’s answering machine play over the opening credits, which appear on a black background—serves as a nice introduction to the current state of the relationship between the two main characters.
Grant and Parker, who have surprisingly little chemistry together, futilely try to make their flat characters interesting. The best performances in the movie come from Sam Elliott, who plays Clay Wheeler, and Mary Steenburgen in the role of Emma Wheeler. Jesse Liebman and Elisabeth Moss are quite good as Paul’s assistant Adam Feller and Meryl’s assistant Jackie Drake, respectively. Seth Gilliam, who plays Ellis Carver on the TV series The Wire, has a small role as U.S. Marshal Lasky.
