I just saw this for the first time and it is the most interesting movie I have seen in a long time
I had the benefit of watching it with sub titles so my experience may be different from most
I have been fixing aircraft for 30 years so I have to watch/read movies to enjoy them since I can't normally understand any movie I watch
Once I watched it, I immediately watched many explanation/easter egg vids
Then I watched it again, and plan to watch it several more times
I actually enjoy watching the You Tube vids as much as I enjoyed the movie
I saw one with the fight scene synced up from both perspectives and do not understand how any mere human could direct and compile that sequence almost flawlessly
I was amazed that people could convincingly act "inverted" in some of the inverted scenes
I'm going to watch more You Tube vids about it now
