A lot of you seem to be confusing “So, You Think You Can Dance” and “Dancing With the Stars”...
The first has young, talented, and primarily unknown people dancing. It’s like American Idol for dancing but seems to really try to involve the dancing community for what it’s worth. The participants are into it, the choreography is generally good, and some of the talent is really amazing…
The second is “stars” dancing with professional dancers, mostly so you can laugh at them and notice them. I’m guessing they get paid quite a bit more than those in the first show, most are apathetic, not talented, and for some reason it seems to be a bigger hit.
