A lot of people criticize his movement on stage now compared to pre Encore performances and such but I think more recently he has definitely improved and I've noticed a few different things he does. A lot of it now is better than that drugged up 2005 New York performance.
This for example...

Around 1:20, that thing he does with his feet looks pretty cool
I'm glad he stopped the 'duck walk' or at least cut down on it a bit because that just made it look like he'd shit himself. He's definitely loosened up a lot more since the shows he did when Relapse came out. He looked very stiff there and you could tell he wasn't used to the performance side whilst being sober, however I think he got away with it because it weirdly suited the Relapse theme.
Just thought I'd point this out anyways!
