I don't think I posted about this, but recently finally caught Tenet. My in-laws have a home theatre, so we got to watch it on a big screen, which is definitely the way to go. I've always been a big Nolan fan, but I wasn't really a fan of Dunkirk. I thought it was a technical feat - the way that he played with three different timelines that converged with ingenious and seamlessly integrated, but it felt like it had very little in the way of substance. Conversely, Interstellar was so much of everything, and one of his most human movies, even if the ending was a little silly.
I felt similarly about Tenet as I did to Dunkirk. First off, my wife and I are huge time-travel fans and absolutely love stories that mess with time. We've watched just about everything out there with good time travel work, we love to discuss it, and our bar for what is difficult to understand is probably higher than most. That said, neither of us found the time manipulation to be particularly confusing. Just like he does in any of his twist movies (especially The Prestige, which is still my favorite Nolan movie), he gives you the keys to the puzzle early on, you just don't know it. Only, in Tenet, it seemed very obvious when a character said something that was going to be obviously important later on. Similarly, the structure of the movie became very clear at least by halfway, if not before, which put together the major pieces of the first half almost immediately, and later filled in most of the gaps.
The action was fun; because we were in a theatre, we didn't have any sound issues; Washington was solid and Pattinson was, unsurprisingly, fucking amazing. I enjoyed Branagh as a villain, but his story was...kinda dumb. Overall, I don't think I'll ever feel a desire to see Tenet again, but I'm glad I watched it. It was fun.
