The MCU has its own issues, of course, but I think it's worth noting that in the TV series, they were more than willing to experiment with lower-action formats. She-Hulk is the biggest example, and it looks like WonderMan will be another one. But even some of the core shows, like WandaVision, Loki, Ms. Marvel, etc. were confident enough to let entire episodes go by without a big action set piece. Not to mention shows like Hawkeye, or Agatha All Along, which were relatively light on VFX.
I'm not a fan of "blame Kurtzman" at all, but every time he writes or directs a modern episode of Trek, it seems to have lots of "pew-pew." He really seems like the guy in the room pushing this.
