Tenet is not a movie, it's more like algorithm or scheme. But not a story in its usual form. Dramaturgy from another time-line where Nolan completely lost interest tell story about humans.
I love that in Tenet main characters are concepts and if you think about it, you can do a lot with that idea and to fully understand you need see movie more than once or twice. Actually puzzle that movie dictates is not hard but shown to audience in strange way.
