I hated that Chloe was made to feel as if she didn't do a good enough job, when she lost by a tenth of a point. That small a difference could just come down to one judge's preferences. It doesn't mean she did anything wrong. Abby admitted in her voice-over that boys often get preferential treatment, but she can't just congratulate anyone on a close second.
I saw both the last two episodes last night, so I might be condensing them all into one show, but I also really disliked the fact that Abby seems to ignore an achievement by anyone other than Maddie. She put Nia in as dance captain for the very first time, a job she said would be difficult, and the team won. How come no "Good job, Nia!"? Why did Abby instead immediately ask to see Maddie's Drop Dead Diva dance, which she could have asked to see anytime? That put everyone, including Maddie, in a terrible position. Abby's feud with Cathy (and vice versa) is, I agree, way out of hand. And I do wish that poor Vivienne, who really is being used as a human prop, would be allowed to find an activity of her own choosing, away from her mother, in which she could find personal enjoyment. I really don't get the sense that she's even that happy about dancing but simply has no choice about it. Her mother owning a dance studio is no guarantee that she's going to be a great dancer or even want to dance. Maybe she'd be happier playing soccer or taking piano lessons or any one of a hundred things little girls try before they decide what they really like and what they're really good at.
As sort of an addendum to that, I wish Abby would stop acting as if all the students at her studio are there training to be professional dancers. Most of them are not going to dance for a living, and even those who are, aren't going to do it forever. Eventually, they'll have to move on to something else. Wouldn't it be nice if they developed other interests to pursue?
What continues to amaze me, though, is how genuinely supportive the girls are of each other, despite all the squabbling, name-calling, and otherwise immature behavior among the supposed adults around them. Well, that, and why Holly is still there. She seems to understand that dance is an activity for Nia, not a life's calling, and both she and her daughter seem reasonably grounded. Why are they sticking it out in the midst of this bickering, nasty mess? Surely there's more than one dance studio in Pittsburgh where Nia could be happy.
