At the 16-minute mark in "Tenet" one of the characters says, "Don't try to understand it!" I was already confused, but after two more hours I realized that line was a clear and present warning of confusion to come. A bigger screen or subsequent viewings are NOT tempting prospects. What is tempting is to go back in time and retrieve that 2 hours and 31 minutes. Mr. Nolan, can you help me?
