I saw this a few weeks back and will definitely be watching again, ideally in an IMAX theatre once and if that ever becomes possible. It is probably the most challenging Nolan film. It’s convoluted, ambitious and maybe it makes no sense yet I enjoyed it a lot. He takes his fascination with playing with timelines and perspective to a whole new level here. We have seen this thread before starting from his first movie Following through The Prestige and Inception. Even what should’ve been a straightforward war story in Dunkirk had some odd timelines and story telling. All that is to say that this Nolan dialed up to 11 and it will not work for everyone. It worked for me.
