Tenet (out Aug 27) gave me a similar vibe to Christopher Nolan's 2014 sci-fi epic Interstellar in that it's a flawed masterpiece. It’s got a quality cast, moves at an energetic pace, and features a heart-pumping film score... but it's squashing 20 hours’ worth of ideas into 2 and so the end result feels rushed, fragmented and, at times, incoherent. Still worth your time. Grade: B.
