The beautiful thing about these types of discussions is that there is no wrong answer. Whether movies (and all stories regardless of the media through which they are told) are good or bad is completely subjective. Candidly, I think there are some crazy answers in this thread. People hate movies I love. Some of those movies I love are "good films", others are just fun movies. I won't criticize any of those folks because it is subjective and I know there are movies they love that I hate. A guy I used to work with captioned this well in discussing music. His point was that he never criticized what anyone has on their iPod (tells you how old this story is) because all of us have some cheesy crap on our iPod, so no need to take it down that rabbit hole. He was a nutty guy, but I thought this was well said and applies here.
I say that as a lead in to object to the point "there's no question he's incredibly gifted and one of the world's best" point. There are many that agree with that. To me, no, I don't see one of the world's best. I've not seen many of his movies (Boogie Nights was entertaining, but not great, and There Will be Blood was just horrible - we couldn't even finish it - as much as I love DDL, all his rambling monologues was torture), but the descriptions of the stories aren't appealing and I don't want to see any of his other movies (looked at IMDb just to see what else was there). Frankly, I hadn't heard of his other movies besides Punch Drunk Love, which doesn't appeal to me. If that's what you enjoy - awesome, I'm glad they are there for you. But it is extreme to say there is no question he is one of the world's best - just have to disagree there. Of course, maybe I'll love his next couple movies and change my mind.
On a side note, I'd like to add The Irishman to this conversation. Way too long telling a story with very little substance to it. The bit about painting and an assassin in the mob was intriguing. But him playing peacemaker between the mob and Hoffa when it is plan as day from the beginning that he will kill Hoffa (because we all know that story) - it was very overrated. And I was really excited to watch that movie, but it was a huge letdown.
I work in the industry and it’s my artistic medium. PT Anderson is one of the best living filmmakers, if you understand the craft. Like I said, I even hate one of his movies. But his filmography and accomplishments are ridiculous.
