Their dancing is simply not good.
Sorry but this is probably the nicest thing I could say. I was honestly stunned at how poor this was (I read all the posts here and then watched the video - y'all didn't prepare me for this). The technical deficiency is so apparent that I can't even look past it to discern choreo/costume positives.
Their hearts are! They don't deserve to be made fun of (I have seen this on FB posts) but they don't deserve to win or even get a call back.
Yeah I'm trying to keep this in mind but frankly it looks like a novice Showcase after a few months of lessons. Admittedly I'm steeped enough in this world that I've watched enough paso so my expectations are likely skewed. I remember a judge once telling me that a Showdance score under a certain number (in his scoring paradigm) meant "the instructor should have never let this on the floor" and this reminded me of that, at least in this context.
There are times when good intentions/desires do not excuse lack of execution. This is one of those times.
