A dynamite ensemble cast and a truckload of heart keep the sentimental new comedy POMS from crumbling beneath multiple well-thumbed clichés including (but not limited to) plucky underdogs can triumph, friends are really important and life is short so live it fully.

It makes no sense that this fun, feel-good movie about senior citizen cheerleaders should waste so much precious screen time on miserly Keaton hacking up her Metamucil or whatever. If you’re going to make a movie about elderly cheerleaders, bring some brio and physicality to it.

Poms is strongest when basking in the infectious enthusiasm of its cast. Keaton and Weaver could have easily phoned in their performances, but they do look like they’re having fun together with their crew of Golden Girls.

The feature’s heart is in the right place, especially in advocating that age shouldn’t be a barrier. But Poms is a by-the-numbers feature which couples its empowering message with routine gags and muddled conflict.

Poms really wants to be a sweet movie with a sweet message, but it’s hard to buy into it when none of the squad gets significant backstories, inner lives or even enough dialogue to give them distinct personalities. They’re just there to be punching bags for other characters and the movie.
