Filmmakers have learned how to optimize for a very specific kind of "excitement", but I disagree that movies are more exciting now than they used to be.
The most exciting and engaging movies I can think of are all pretty old.
Peak movies in terms of both tickets sold and total real revenue was 2002. Everything since then has been a rapid decline, paired with lots of inflation and ticket prices going up even faster than inflation. I'd also add that those data don't consider another aspect. Since 2002 the US population has increased by more than 45 million. Seeing ticket sales plummet alongside this is especially telling!
So, while you may personally find what passes for a movie now a days as "more engaging", even "the masses" would beg to differ!
Alternative read: the industry is dying so they double down on pandering in an ultimately futile attempt to bail out the sinking ship.
Consider anime: It has been a dying art ever since Japan's economic stagnation/recession in the early 90s. So the anime industry (generally, with some exceptions) turned hard into pandering to their most base fans, lonely dudes. Lots of waifu characters designed to sell body pillows and trash like that. This hasn't improved quality and sales continue to slump, but they're still trying.

If you are looking for movies that focus on strong dialogue and character work those movies are still being made and are fantastic.
My favorite films would include Das Boot, I Claudius, and Seventeen Moments of Spring. For something more contemporary, I also enjoyed The Expanse. Any recommendations? Films or series in any language are okay.
