Tenet: 10 Reasons It's Christopher Nolan's Worst Film Ever

5. The Science Is Complete Nonsense

In the trailers for Tenet, all the time travel stuff looked intriguing but also pretty baffling, so there's no doubt everyone was looking forward to having the mechanics and rules of Tenet's world explained properly in the film itself. Sadly, you'll come away even more confused than before.

Early on, a scientist (Clemence Poesy, who Harry Potter fans might recognise as Fleur Delacour) explains some of the mechanics to the Protagonist (John David Washington) and says, "Don't try to understand it." In that moment, there's a sense that Tenet has already given up trying to explain this preposterous nonsense.

Everything involving the time travel gets more and more confusing and ridiculous as it goes along and since there are so many gaps in the viewer's knowledge of the world, it often feels like an unfinished screenplay.

In fairness, maybe the time travel in Tenet was actually explained... only no-one could hear it thanks to how awful the sound design was.
