Maks is usually the biggest supporter in this, but I've seen many pros say the judges don't help when they don't give constructive criticism, so the pro knows what the celeb is doing wrong and what they need to work on. Maks brought up several points last season in his blogs, about just random things the judges found wrong but didn't really give him anyway of knowing what the big issue was or how to work on it.
This show started out as taking non-ringers and pros out of their comfort zones and teaching them to ballroom dance. They at least deserve respect for trying, especially the second week. But, it's the same old story every season. Some of the current favorites will probably get thrown under the bus at some point as well.
