The 70s, 80s, and 90s do have commonalities in the action movies of each era and I feel like those probably exist for the 00s, 10s, and 20s as well though I can’t identify them yet.
The Noughties saw Wuxia break into western cinema with Crouching Tiger, Hidden Dragon and we saw the start of the resurgence of the superhero movie, Blade 2 into Batman Begins and then the start of the MCU with Iron Man.
Also, The Matrix dropped in 1999, so it’s influence really only started to be felt in the 2000s, most obviously with Equilibrium but note generally with an improvement in action choreography across the board (ultimately leading to the John Wick films that pulled in a lot of the ideas and people inspired by The Matrix - Chad Stahelski being a common factor in a lot of the key action movies of the 21st Century).
