Spoiler review!!!
Nolan had a concept. But the execution is far from perfect. People who think they are smart and only extremely intelligent people can appreciate it are just die hard fans who don't want to admit that Nolan failed to fully create a world with rules that work in some cases and in others don't.
In a movie about time,There is literally no time to explain anything, yet in some scenes they spend a lot of time explaining props that are not even used.
The scientist explaining inverted bullets, there is not a single scene where a normal timeline person fires that inverted bullet coz it doesn't make sense.
The airplane scene, really sounds stupid when you realise they went through all that just for a painting.
The movie did keep me on the edge and I was waiting for point where everything will finally come together in the climax(The Prestige)
But Tenet fails to do that and things are just wrapped up expecting audience to "not try to understand, feel it"
I couldn't feel it really.
