What could have been a very straightforward (and yawn-worthy) doc about tennis’ Superbrat is instead a probing and raw examination, and Mac himself is holding the scalpel. Set alongside a through-the-night stroll in New York City, the film takes us inside the mind of arguably the best to ever play the game, and director Barney Douglas makes sure this isn’t a by-the-numbers ‘he was bad but he was really good’ bit of fluff. Featuring present-day interviews with everyone from Bjorn Borg to Keith Richards to McEnroe’s own kids, it’s a revealing and fascinating journey.

4/5 stars
