As Jerry, Jeremy Renner brings the full force of his Avengers, Mission: Impossible and Bourne franchise action background to the role, completely selling the "untaggable" concept as he dives out of windows, uses parkour to scoot up walls and uses a granny's handbag as a makeshift nunchaku to fend off all those outstretched tagging hands.
The humour's largely improvised and while some of the jokes don't land as hard as they could, the movie's good spirit and the camaraderie of its leads - and those scaled-down blockbuster set pieces - keeps you involved throughout.
Based on a true story about a group of mates that really have been playing the same game of tag for decades, the movie hits some surprisingly poignant notes on friendship and growing up, without growing old.
It's not the sort of movie that will win awards or top critic's "Best of the Year" lists, but if you're after a breezy, funny watch, then Tag is it.
