Tenet was such a gimmick
If you didn't have the whole "omg we're inverting!" mechanic, the entire movie is pretty much worthless, other than Nolan's love for grand IMAX shots of industrial shit.
4/10 would not watch again
Also, the dialogue in his movies is ALWAYS hard to hear/decipher. ALWAYS. I don't know what his ****ing problem is. It's like he wants to make the audience suffer.
If you're introducing such a wacky concept in a film it needs to be clearly and SLOWLY explained. The universe building in this thing was terrible.
