June Squibb portrays Grandma "Thelma," who falls victim to a deceptive scheme involving her grandson “Daniel” (Fred Hechinger), supposedly involved in an accident with a pregnant woman, resulting in the loss of $10,000. Her family subsequently discovers the scam, but Thelma isn't willing to let it go. Enlisting the help of her friend "Ben" (Richard Roundtree) – or, more precisely, borrowing his mobility scooter – she evades her family’s attempts at protection and sets out to locate the person responsible. Squibb and Roundtree seem to be genuinely enjoying themselves as they participate in a series of amusing escapades that demonstrate how strong a person's spirit can remain even when their physical abilities decline; Malcolm McDowell’s presence also suggests a satisfying conclusion is likely. I felt Hechinger occasionally overacted, but his performance still offered some entertainment and he had a nice rapport with the delightful and remarkably clever Squibb. Clark Gregg and Parker Posey round out the family cast, providing amusement as they portray parents navigating the challenges of caring for an aging relative while also attempting to maintain their own lives and monitor a son who has recently experienced a breakup. The film does falter briefly in its final stretch, struggling slightly with how to convey the absurdity of a stubborn person’s actions, but overall there are plenty of moments to chuckle at as they progress. It may not stick with you for very long after seeing it, but it provided an enjoyable time and reinforced something I've believed for quite some time. Those motorized scooters really ought to have their own dedicated space!
