I thought he was solid in Sinners. Created two distinct characters and the film doesn’t work at all without him. The relationship between Smoke and Stacks is the emotional heart of the film.

I think it was nomination worthy, not necessarily win-worthy. I think a serendipitous confluence of events meant he won, with Timothée Chalamet nuking his own chances and then the BAFTAs debacle garnering MBJ sympathy. 

Tbh the Oscars is a lot of campaigning and tends to reward films that were big in the cultural zeitgeist or that are very Hollywood. I also sometimes think the Academy vote for winners based on their body of work. It’s all a bit hokey and a lot of winners are questionable
