Channing Pomeroy’s review published on Letterboxd:
Christopher Nolan may have hit on the algorithm to save Hollywood — a blockbuster that serves as its own sequel. You only have one production budget, but you make everyone see it twice.
On the first viewing “don’t try to understand it, feel it.” You appreciate the palindromic action sequences, the Bond-like globe-bouncing locations and radiant star performances.
But you have to go back and shell out another 15 bucks to try to figure out what the hell was happening. Understanding it better after the second watch definately raised my appreciation. However, unlike Once Upon a Time in Hollywood, which rewards you on a second viewing with new layers of meaning and emotion, Tenet just takes two tries to unfold Nolan’s most complicated temporal origami creation.
Will we get a sequel, or have we already gotten one? Will there be a future in the past, or is this the end of a beautiful friendship?
The Protagonist: Hey you never did tell me who recruited you, Neil.
Neil: Haven't you guessed by now? You did! Only not when you thought. You have a future in the past. Years ago for me, years from now for you.
The Protagonist: You've known me for years?
Neil: For me, I think this is the end of a beautiful friendship.
The Protagonist: But for me it's just the beginning.
Neil: We get up to some stuff. You gonna love it. You'll see. This whole operation is a temporal pincer.
The Protagonist: Whose?
Neil: Yours! You're only half way there. I'll see you in the beginning, friend.
