Here I am on a Sunday morning, sipping coffee and feeling glum as hell about the films of Joel and Ethan Coen no longer being part of our world. They haven't been, really, since Inside Llewyn Davis, the last bona fide Coen Bros. flick (low key, early '60s folkie vibes, slurping cereal milk, Schrodinger's cat). It opened almost exactly a decade ago (May '13) in Cannes.
