Well, it's not wrong to (or not to) subscribe Disney+ and AppleTV+. Even Netflix started by buying K-dramas, and investing in some of those in production (To be exact, Mr. Sunshine, which they invested half their budget to get the right to air the show to 190+ countries).

Today most of the production companies and the TV stations are pretty separate in terms of production itself, even though they may be under the same corporation (Like Studio Dragon and tvN both under CJ E&M). What Netflix has done well is to invest in studio themselves, so they can produce their own show (Kingdom and Squid Game are two of those examples), and give screenwriters as well producers a lot more freedom to do what they want (Some of those shows, also Kingdom and Squid Game, can't be aired in even cable televisions). However, More foreign companies may also result into K-dramas doesn't look like K-drama, Jirisan is actually one of those. What I really want to is, even some of those dramas are adaptation, I want them to have some Korean elements, like Designated Survivor: 60 Days, The World of the Married, and currently, Inspector Koo.

Other then their own production studio, Netflix done well because they open an office in South Korea and ask local talents to get the right show, and The Swoon, the YouTube channel exclusively showcasing K-drama clips (are they choose it well, that's another issue).

I do think he’s improved, but as you said yourself, it’s in smaller roles. A leading role is a huge jump up from that. And Chae Soo-bin is immensely talented. I’m afraid that gap will be obvious unless he’s improved significantly à la Yuri in Bossam. On the contrary, It’s always a delight to see great performances from unexpected places.

As for why I commented about him in the first place; well, I don’t think there’s anything wrong with having honest criticisms of an actor’s capability. Especially as consumers of their work. This applies to every actor, not just Minho.
