Felt like a combination of Memento, Inception and Interstellar. Nolan never ceases to amaze me.
I thoroughly enjoyed it—went in 100% blind except knowing the cast and that it was a Kaufman film. I determined the twist from the get go and picked up connections early on (writing this to avoid spoilers) so I was able to stay focused and understand the film (at least I think I was!). Watching Jesse Plemons and Toni Collette eating dinner together was the highlight—the only thing better than each acting apart is the two together as they are both such strong actors without being overbearing).
