Clive-- having taught in the states for many yrs,let me assure you, that the top flite pro,s seldom get involved in the " theatrics " , that is so pervasive in ALL t.v.programs, no matter the country of origin ( can you ever imagine marcus doing this !! )
programs that portray " their " version of what the public will be allowed to see , is unforunately dictated by public taste .
having said that-- i cannot ever imagine, for e.g.-- why an authentic T / Arg or Q .Step for openers, would not find a captivated audience .
Much has to do with music availability . I doubt there is one band, who has the correct musical scores ( and or instruments ) to cater to all the different genres being performed .
When producers with little or no dance background are involved -- well-- youve seen the results!!
