That dance mums is really bad I agree - it's one thing to behave badly and become a suprise hit (like what happened w/ the first dance moms) cause at least it was an original idea and a lot of the underlying tensions and history were geniune, but it's pretty lame to emulate someone else's bad behavior to grab some of the residual leftover fame from someone else's idea. I don't believe for one second that any of those moms really act like that - I think it's all performa/scripted for the show.
The dancers are very good though.
