No, not the water, that's Pellegrino.
From my time on some of the other Hapkido forums, I have observed that many Hapkidoists really despise master John Pellegrini, calling him a fake and a fraud, and criticizing his Combat Hapkido style as being incomplete or "not real Hapkido".
I don't mean to open up a can of worms on this website, but I just watched two of Pellegrini's Combat Hapkido demo videos on Youtube, and his stuff looks like good, solid Hapkido.
The embed links are disabled for these videos, but here's the link to the first one:
I admit that Pellegrini does not have that super-fluid, devil-spirit-in-motion dynamism of some of the Korean Grandmasters. But consider that Pellegrini is an old man in these demos, and he's tall, which makes him seem ungainly.
He is clearly skilled. His Hapkido looks good, and his moves are sharp. So what if he dispensed with high kicks and chose to focus on hand strikes, joint locks and low kicks? Frankly, that would work very well for someone like me with bad knees. I'd sign right up.
