It was the worst movie I've ever seen. As in, that I paid money for to go and see at the cinemas. So yeah I've seen maybe one or two worse, but believe me Tenet belongs at the bottom of the barrel
How can anyone like a movie that is so inhumane? The characters have no depth to them at all. There is 0 character development, 0 back story, 0 reason to care about any of them on a human level. That's why I call it an inhumane movie, the characters might as well all be robots. But hell a decent movie can even give robots humanity and character. I, Robot; Blade Runner. The robots in those movies were more human than the characters of Tenet. And that's why it's such a horrible, horrible movie.
Why does the plot even matter? "Oh no the bad guy is going to end the world! The tenet crew have to save the world!" But who even cares about this world of the movie, which doesn't have a single human person in it? So what if that world ends?
Compare it to inception. Same bullshyt director, Nolan. And he was on his same bullshyt science fiction that nobody can understand as the main plot line. Its basically the same movie as Tenet, it has the same formula. But it was SO MUCH better because DiCaprio's character was actually a human being with hopes and dreams, with regrets from the past and desires to make amends for the things he regretted. With an estranged family and children who he dearly cared for and desperately wanted to be with again. Inception had a strong human character, so it was a top movie even despite sharing a lot of its other stuff in common with Tenet.
You can't have a movie without strong human characters, it just doesn't work
