I think most of the situations on the show are contrived and most of the drama is forced but I think, at least, the kids' reactions are real. I was watching an interview with Maddie a month or so ago and she was talking about how, at the beginning of Dance Moms, she didn't quite grasp that what was happening was for the show but after a while she learned to deal with it.
I do feel bad for Abby because her life is rough and shes all alone - no mom, no dad, no siblings, no SO, etc. Shes wrapped up in the entertainment industry where everyone is out for themselves. I imagine her next few years will be VERY lonely and for someone who clearly needs affirmation from other people, its going to be rough for her. Even if she's 100% at fault for her actions and reactions, I still feel bad for her. That's not a life I'd ever want and I hope she comes out a better person in the end. I'd like to see who she turns into after hitting rock bottom.
