Bruno definitely isn't as coked up bad this year.
I think Anton is mainly annoying when hes paired with a duffer and starts being "hilarious" to fill in the awkwardness of standing up there with Claudia waiting for the inevitable 2s and 4s. He just goes "fuck it" and loses his head and starts plunging over the metaphorical cliff.
But he's ok when he's really interested and enthusiastic. So I think judging might be a good fit - there's no stakes for him personally, his opinion would be respected, and he'd have a 30 second time limit, lol.
And at least he's a dancer who's had to perform every damn dance under the sun in his time on the show so knows what every dance is like to actually do. I like Darcy, but would prefer her if she actually had a ballroom background rather than ballet as I doubt she's ever done a Charleston in her life (for example).
However the producers are the ones who hired Aleesha. So it's quite possible that the new judge will be a "Personality" like her, and none of the above. Which would be shit.
