He does a lot of very Hollywood-looking moves, very quickly, while looking the part, and being sorta enigmatic by not explaining much. And perhaps most important, he has managed to get passed around outside the normal training junky circles, which only adds to the awe from people who don't know different.
His earlier videos were a bit sillier, with the rolling and whatnot. The speed shooting is not as bad. All in all, he seems like a very skilled shooter, and I've got no reason to bag on that aspect... but the rest comes across as almost a self parody. He should hook up with the Dynamic Pie guys.
Meanwhile, this thread needs less talkydiscussy and more silly raps.
