When a movie mentions the one-electron universe postulate, you know it's different! Tenet is a skull-mangler, thought-provoking flick. Brilliant direction and riveting cinematography.
My favourite section from the movie is the transference of the algorithm between the protagonist and the inverted protagonist. That part is bonkers! A subtle symbolism that I really liked was the scene wherein the protagonist is being tortured and two similar-looking freight trains are shown coming and going simultaneously, alluding to the converging arrows of time, a narrative of time that's woven into the fabric of movie's storyline. I noticed it in my second viewing. It is surely a movie which rewards multiple viewings for the viewer begins to peel through the layers, and unravel the depths, of nuanced storytelling. Also, the soundtrack is epic!
The movie's going to satiate all the movie aficionados, particularly the sci-fi enthusiasts. In my opinion, it is one of the best offerings in Christopher Nolan’s oeuvre. Enjoy the ride!
