Having nearly three fourths of the dialogue in your movie be scientific terms and concepts doesn’t make your movie smart.
“Tenet” follows a character simply known as The Protagonist (John David Washington). A spy who appears to work for the American intelligence apparatus, Washington’s character is assigned a mission where he has to investigate weapons that defy time.
For example, the spy is shown bullets that are inverted, which means they move backwards in time. On his mission, the Protagonist is assisted by a helpful contact named Neil (Robert Pattinson). As the mission continues, the Protagonist discovers the main person associated with the weapons is Andrei Sator (Kenneth Branagh). To get close to the arms dealer, the agent begins speaking with Sator’s wife Kat (Elizabeth Debicki).
