🎬 MovieFinder's Take

The film operates in a light register — but not superficially. Behind each joke is an observation about people, not just a desire to amuse.

Goes down easy, leaves a good aftertaste. Not every joke lands equally — but the overall tone holds.

For those who just want to relax. Asks nothing — just time and a willingness to smile.

Director: Richard Benjamin
