I used to love FMA but after grappling for the past 8 years I have to say, this looks ridiculous. I have a 25 year history of FMA and JKD, being a certified instructor in the latter. I see JKD videos now and I think the same thing. Garbage. The reason it looks ridiculous is because the defender is getting like ten moves to the guys 1. Fighting doesn't work that way. Plus, any technique works great when no one is resisting. It's like you are creating a false sense of security that you can do all this cool stuff without and opponent closing the distance or fighting back at all. You can't.
