Oh, really? The terminology can be confusing))

For example, which ones?

This site is more suitable for getting acquainted with Japanese projects. I recommend it... https://japan-programcatalog.com/en/

Can you tell us more about the difference in quality?

In any genre, in any country, there can be both good and bad projects; and projects you might like and those you might not. It is okay. Good luck with Japanese series/movies.

Yes. She is his mother and sister

Interesting choice.

Then you can also watch this. But I warn you, it's not for the faint of heart. A very heavy film.

Hong Kong action movies are good. I like a lot of their films.

Japanese detective and horror films? And what are some good ones?

In fact, they have many live-adaptations about the Yankees. The Japanese never stop romanticizing their crime. They have many projects of various genres about both the Yankees and the Yakuza.

The most popular manga is "Crows". And its live adaptation became a classic. If you are really interested, I also recommend it.
If you read manga, I recommend checking "OUT" (there is a film adaptation too, but it is terribly bad...)

Tokyo Revengers? Yes. Look https://www.youtube.com/watch?v=APlViqlE8PQ

The level will be the same as in "High&Low." That series is very popular in Japan. The first arc of Windbreaker was heavily changed, judging by the trailer, and it reminded me a lot of "High&Low."

I'm sending you short excerpts from fight scenes.And decide if you like it. Because it'll be the same level in Windbreaker .

This is true. But.. They've made a lot of high-quality live-action adaptations, but they don't promote them at all. They make them purely for the domestic market.

Yees. They nice

They don't have stuntmen. They did all the stunts themselves. As far as I remember. The company that produced this series trains artists of all calibers.

A competent team is working on the film. The Japanese always have high-quality choreography. Moreover, this is a film in the Yankee genre, and this genre has been thriving in Japan for a very long time. If you're interested, I recommend watching series High&Low https://mydramalist.com/list/mLArokA3. This series inspired many manga artists.
