It's one of those movies, that wants you to think that it's clever, that it's Nolan-esque while actually being incredibly average and uninspiring. The idea is a well-established one, execution subpar, acting decent, Sarah Snook carried it. It's very dialog heavy, don't watch it if all you came for is the action, it's literally not even 2% of the film, majority of it is just Sarah talking with Ethan in a bar. I didn't understand it, it was confusing and the ending didn't help, it reveals absolutely NOTHING so be ready for that. It's not gonna impress you, nor disgust. As I already said, Uninspiring.
