On the first viewing, Tenet is indeed all feeling. If you want to grasp fully what exactly the film is driving at, guess you'll have to give Nolan's characteristic mind-bender one more shot.
Tenet furthers Nolanโs abiding interest in proving that cinema itself is the greatest time travel machine ever built. Memento, The Prestige, Inception, Interstellar and Dunkirk have all played with narrative linearity and conventional dramaturgy to demand that we watch very closely and return over and again to make sense of what we have seen.
