He's fine, an excellent technical director, but I wouldn't list him as the best. I like that he brings a lot of craft and some thoughtfulness to BIG cinema. Arrival is one of my favourite Sci-fi films of recent years and Blade Runner was good.
Others have already offered replies with much more interesting active directors though. For me no-one's work excites me as Lynch. PT Anderson is top tier. Don't think anyone has mentioned Kelly Reichardt but I love her films, they're typically quiet but so impactful.
Coens, McQueen, Gerwig, Chloe Zhao, Wes Anderson, Fincher, Tarantino, Bong, Eggers, Lanthimos, Spike Lee, Cuaron, Aronofsky, von Trier, Waititi, Scorsese, Pawlokowski, Peter Strickland, Herzog, Charlie Kaufman, Park, Linklater, Spike Jonze, Lee Chang-dong, Barry Jenkins, Nuri Bilge Ceylan, Debra Granik, just to get started with, have all produced great films and are active directors whose next project I'd look forward to before Villeneuve.
