I have seen no dancers on TV talent show even close to the genius of Fred Astaire and Ginger Rogers. Why?
Where are the brilliant Hollywood dancers of the 1930s and 40s? Most of the dancing on 'So You Think You Can Dance' seems to be nothing more than pumped-up gymnastics.
Because they haven't been training as dancers their entire lives. If you want to see a better dancer than Ginger Rogers try looking up Youtube videos of Eleanor Powell dancing with Fred Astaire, now that's something to see!
