I said it before and I'll say it again...liturgical dance is neither!
I know what dancers are supposed to look like, and these "liturgical dancers" aren't it!
The problem with these folks is that they could never get a real gig. They not only aren't good enough, they aren't even within shouting distance of good. So they go to church and inflict their horrible travesties on folks there . . . mostly because the sillies who let them do it don't know anything about dance.
Of course, it's also not appropriate for Mass . . . but the icing on the cake for me is that it would be awful wherever it happened to be.
