Some media regarding Maks vs Len-and even though I was already on Maks's side, I still think the judges don't get it. I wish he had hashed it out with CA again. Not as many people like her, and I would have loved to hear what Maks said in response if she said 'I've been in this business a long time'. The producers have to be loving this. It's the only watercooler worthy thing that's happened all season with a chemistry free and boring cast. Even controversial castings didn't deliver.

I think this brings up contradiction on the judges part, and why Maks's rant had more merit than his beef with CA over Brandy. For some, they criticized the performance of the night, week after week, whereas with others, they withhold scores because they have the potential to be better

So I think Maks was right in calling them out and saying they don't deliver fairly to anyone. Saying it's their best/worst dance of the series (sometimes in week 3), doesn't help them get any better.

In terms of Maks saying it's "his show", I don't think he meant it literally. I believe he meant he was here when it started, along with most of the pros who've been around since the early seasons, they've become as much of the show as the celebs and judges, and people expect certain things from them. At least that's my take on it.

I liked this comment from Maks. Goes along with what the judges have said in the past about it being a TV show, so no one should be offended by what they say. They can't judge, and I'm glad they get taken down a few pegs (if not by the pros/celebs, then by the booing audience-annoying as they are the minute they hear something negative, I like CA not being able to take it).
