AnthonyMartel’s review published on Letterboxd:
Tenet left me baffled. For starters, I didn’t understand half the dialogue because it’s one LOUD movie. The characters falls flat because they don’t have much going on. So, you won’t have any emotional connection to the picture and you might be a bit annoy/frustrated that you can’t hear everything.
On the other hand, Nolan brings an amazing twist to action films with mind blowing set pieces that are really sophisticated. It’s the kind of thing that only a master of cinema can direct. At some moment, you can only be amazed by the spectacle offer to you through originality and brilliance.
If you want to see a unique concept and take on action that lacks behind narratively. I would recommend, but if you want to be attach to characters... this isn’t for you.
