To me PTA is in a different league than any other contemporary director.
While I tend to look forward to his work more than anyone else's, I would never make this claim because there's no way that no other artist is achieving similar levels of greatness. I mean, this isn't only a hunch. It's borne out by my own viewing experiences. There are many unusual and great movies out there! There aren't really other
truly PTA-esque movies, sure, but no one is perfectly matching Spielberg's standard, either. Those are both great filmmakers partly because their achievements can't be precisely emulated by others and their work often refuses to be forgotten in a good way. But there are many others who are also great in different, and sometimes similar, ways...
None of them however is nowhere near as ambitious, intelligent, unique and well-made as Phantom Thread. Is there any other director nowadays who at least tries to make something truly unique or moving or at least impressive?
Based on what I've seen: James Gray, Terrence Malick, Luca Guadagnino, Apichatpong Weerasethakul, Ruben Östlund, Lynne Ramsay, David Lynch, Sean Baker, and (potentially) David Robert Mitchell, among others.
Based on what I've heard: Claire Denis and Yorgos Lanthimos, among others.
I enjoy other movies but it's a bummer that for a few years now new PTA movie is the best movie I've seen since the previous PTA movie.
Including experiencing older classics for the first time and everything? Not that you even need to go back that far to find uniquely compelling stuff. Again, while the arrival of a new PTA movie is a major event for me on a personal level -- his writing and visuals are my favourite -- I'm still similarly floored by other movies.
