A clunky, predictable narrative with poor characterisation, repetitive exposition and subsequently flowery uninteresting dialogue that would feel more at home in a student film or a first draft than a Nolan epic. However, the ambitious action set pieces alongside Nolan's technical competence offers redeeming qualities that make Tenet a gorgeous film to see and hear on the bigscreen even if the story itself ultimately feels redundant and at times boring.
That said, I felt the concept of 'inversion' or 'things being played in reverse' translated poorly on-screen often appearing goofy and off-beat. For example, seeing the film's muddled, fat emo super villain running backwards bought laughter to the audience instead of dread - the only thing missing was the Benny Hill theme.
