Digital effects also look a lot worse (as in, less believable) than real special effects, pyrotechnics, etc., and I think the quick editing also has to do with that. You have to make a lot of cuts and shaky shots in order to not let viewers' eyes rest on the CGI's uncanny valley for too long and realise how wrong it looks.
I watched the first Rambo very late, only about two years ago, and I was amazed at how much better the explosions look than in any movie I've seen in the past two decades. You can afford to actually show what's happening when it looks that good.
I've noticed a similar thing in martial arts movies. You can save a lot of effort and money with the quick, frantic editing. The alternative is that the choreography and cinematography have to be really on point. If you just shake the camera around a lot and do a cut every second, you can get away with amateurish fighters doing whatever, nobody will really notice.
