I remember when I was a kid and used to watch Mask Rider Black and other tokosatsu tv shows, the main characters will barely talk and just be broody while noticing things as part of their investigations. It was the villains with the wide smiles, the villainous laughs and cheesy dialogue. This type of cringey acting I don't mind because how how else would an actor show their villainy without laughing maniacally.
But do that with a supposedly cool protagonist in a manga/anime adaptation suddenly express their shock by stopping dead in his/her tracks with wide open mouth just standing in the middle of the frame for a whole 20 seconds. With multiple camera angles to boot. Yeah! Nope! Its like the directors are just filling dead screentime in place of acting because they completely gave up actually directing the actors.
Japan is really regressing when it comes to live-action because their domestic fans just won't let them improve and corporate are too cowardice to take risk. This is the same with their idol industry too. Too captivated to doing the same thing over and over again. On the other hand I'm sure they are seeing the ever increasing soft-power of South Korea in global entertainment. And instead of learning from it they either keep to their stale mindset or they follow the downward spiral hollywood trends.
I actually really liked watching CW shows some 15 years ago. And won't miss even one episode. Nowadays I don't even watch new shows. I can't stand any of them after duds like Wheel of Time where I've been wishing for an adaptation half my life.
Now I just stick to anime thank you very much! Or watch youtube videos where someone builds a greenhouse to breed goldfish or fix scooters in their home garage.
I think they're stuck in their soap opera area. I think American entertainement used to be similar until the Golden Age of TV made serious filmaking the standard to strive for. Down with looking for the next sitcom with fake laughs for 20 seasons, it's now about looking for the next Sopranos, GoT, Breaking Bad.
(And funnily enough now, there's a lot of demand for media that takes itself less seriously. For example, I think the new remake of The Naked Gun will be very popular, because that's something people miss and go to the cinema for, to see big actors do the clowns and deliver pure fun)
Korea is an interesting beast. They somehow manage to make popular and bland their kdramas soap operas with pure art, like Korean cinema was already known for for decades. They seem really open to translate Korean stories for us, there's very moments where a foreigner will watch and think 'I'm too foreign to understand or worse even care', when too many Japanese projects lose foreigners right at the trailer.
And as I said, it's a shame, there's plenty of Japanese filmmakers that DO NOT care for filling their art with the actors in vogue barely out of highschool. For example, one of the best movie out in recent years was Drive My Car, by Ryûsuke Hamaguchi. Not only it's full of chilling performances, but there's even the meta element of the main character mountain a production of the play Uncle Vania, where the actors are playing actors, displaying the full range of their acting ability.
Anyway, I think they'll change the status-quo soon, it's a such shame when they have so much talent there that the fucking seiyus show more expression and ability with their voice alone, imagine if more actors were encouraged to do their work properly and not to phone it.
