Armed with only one word - Tenet - and fighting for the survival of the entire world, the Protagonist journeys through a twilight world of international espionage on a mission that will unfold in something beyond real time.

A visually dazzling puzzle for film lovers to unlock, Tenet serves up all the cerebral spectacle audiences expect from a Christopher Nolan production.

'Tenet' is visually stunning with impressive action and unique concepts, though the convoluted plot and underdeveloped characters receive criticism. Kenneth Branagh's performance is praised, while responses to John David Washington and Robert Pattinson vary. Sound mixing and dialogue clarity are common complaints. Despite issues, the film's ambition and technical achievements are appreciated, with some suggesting multiple viewings for better understanding.
