A nice Jewish boy and his mother travel cross-country while he is pitching a product he has invented.

The film would be slight and completely forgettable except that Barbra Streisand and Seth Rogen have some mother-son chemistry and (I can say with some authority as the single mom of an adult son) there is some emotional authenticity to their exchanges and what fuels them, hence The Guilt Trip.

Okay, so the film is slight, and the script feels like a first draft, but I still like Streisand and Rogen together.
