Didn't think anyone would be flabbergasted. However, I do think it's a good idea for Barry to study his own movements. He's still in young mode doing what he's been doing for ages , but that doesn't work because he's older. My suggestion just comes out of my own personal experience. I'm into film making and I saw my own actions in a video and thought, you know, that wasn't so good.
Sometimes when you get to a certain level you need to go to reset. Barry needs to, in my humble and blunt opinion, (I don't know how to put this any nicer), to not look like a C-3PO on stage. Barry's a professional, and he's humble, and he'll understand. I looked at myself one time and thought, that was clunky, and so I modify. No biggie. Without taking someone's criticism in you can never get better.
