Tenet. I know it became fashionable to hate it, but it's my favorite Christopher Nolan movie because it's just fun to watch, which is not common with Nolan movies.
I think John David Washington and Robert Pattinson have great chemistry. You need to be comfortable with being clueless about what's happening because the story is told from the limited perspective of the main character. If he doesn't know, the audience doesn't know. When he finds out, you find out. So what the movie seems to be "about" shifts a few times based on his perspective and his assumptions.
Yes, it's clearly just an excuse for Christopher Nolan to indulge in impossible looking practical effects scenes and I love it.
Same. Airplanes. Seeing them, being on one, just so giddy and excited every time.
