His films were always only OK at best, unless you are seriously trying to tell me that three superhero movies qualify as life-altering experiences.
Batman Begins was… OK.
The Dark Knight was good but mostly because of Ledger's performance.
The Dark Knight Rises was borderline laughable. Some of the fight scenes were genuinely sketchy and Marion Cotillard's death scene was pure cringe. It should have been cut entirely. The whole movie felt like amateur hour.
Inception was a pretentious, mumbo-jumbo nonsense movie for dumb people and nowhere near as "smart" as Nolan (or his fan base) wanted people to believe.
Memento was… OK.
Tenet was incredibly forgettable and mediocre.
Interstellar had a brilliant OST, looked beautiful and it was fine until...the whole "power of love" absolute bullshit completely undermined the whole G'damned film.
Dunkirk was a bore. Easily one of the most boring WWII movies ever made, even if it did look good.
Oppenheimer was another dull film that, in my opinion, did not even need to exist. I will not dwell on the reasons, because that would inevitably involve politics.
Following was… eh.
He has to be one of the most overhyped directors in existence. His work ranges from OK-ish to good-ish, and that is about it. He makes blockbusters, not genuinely thought-provoking cinema, despite what his fans claim. In my view, he makes movies for "normies", the same crowd that routinely elevates Netflix-produced slop into the platform's weekly Top 10.
Someone previously asked me whether I thought Villeneuve was a better director, most likely as a "gotcha". My answer was, and still is, yes. While Villeneuve also makes "not thought provoking art house cinema", he at least puts far more emphasis on cinematography, atmosphere, and visual storytelling. His body of work is simply stronger than Nolan's filmography, any day of the week.
As for the Odyssey...yeah, I'm not holding my breath.
