Can't speak to Best Actress, but I loved the reaction from a host on NPR's Pop Culture Happy Hour that said something along the lines of every few years, a picture like Crash is named Best Picture. This year, it was Green Book.
We've seen Green Book before, whether it's Driving Miss Daisy or The Defiant Ones or The Help or any other "white savior" movie. It was a well acted representation of a tried-and-true story, but what bugs me the most was that it wasn't a remotely visually interesting movie. I'd never try to lump one of the Farrelly brothers into auteur category, but this thing was so unnecessarily bland it made my eyes hurt.
IMO it should've been Roma by a landslide, but the industries fears of Netflix shut that down. Shoot, The Ballad of Buster Scruggs didn't even get a nomination.
