Barbra Streisand returns to the big screen here, and the result is not bad. Streisand plays Joyce, the long-widowed mother of inventor Andy (Seth Rogen). Out of guilt, Andy asks Joyce to accompany him on a work trip. The secret mission is to hook up Joyce with a long-lost beau. A tight if formulaic script does well enough, but the performers here do a lot of the lifting. It’s a sweet movie, in its way.
