There is a lot about it that reminds me of Modern Wushu, so I am going to guess that this method was one of the primary methods used in the creation of Modern Wushu.
It is hard for me to comment without having a solid understanding of the engine under the hood. Meaning: how does their foundation work, what are the principles of power generation and how does it manifest in action? That kind of thing.
Just watching it, I don’t like it. It strikes me as more of a performance art and looks like aesthetic posturing. But as I said, that is without an understanding of how the system really works. So I am hesitant to make any real judgement because it could all make a whole lot of sense to me if I understood what was under the hood.
I say this with an acknowledgement that many people look at my system and can’t make sense of it either, without a greater understanding of the foundation. So I tend to withhold judgement.
