Bruh there is literally a popular media character called Captain America.
If you were trying to satirically come up with the main character of a state propaganda show, a name like that would probably come to mind. For satire.
Imagine how US Libs would react if a superhero called Captain China started getting really popular.
I don’t know the show so I Googled it. It does look violent but then again a lot of shows I watched as a kid were violent to some extent. The thing with these people is that they want to see ghosts so badly that they start imagining them. It’s the same people that say ‘AT WHAT COST?’ about every positive piece of news coming out of China/DPRK. They can’t accept reality.
Maybe it’s because I only watched it when I was already an adult, but I didn’t even think it was that violent. It was kind of violent, but again, so is anime. And it’s not like there aren’t Western kids shows with that level of violence.
I think it’s the presence of blood that scares the Western crowd. It seems to be a taboo over here, where you can basically get away with as much violence as you want in a kids show (think Loony Toons, Tom and Jerry, etc) as long as you don’t show blood. But even a single drop of the stuff crosses the line.
