A Little scary . Ballroom and Latin dance has come a long way. Even though many of the dancers on the DVD are still at the top ranks of the pro circuit, this is NOT a great showcase. This is nice to watch in order to compare to the styles and skill of today, but not the kind of video you will watch over and over. The only truly spectacular dancing is that of Marcus and Karen Hilton (standard only). They were then, and are now quite amazing. For those of us in Canada, Alain Doucet and Anik Jolicouer are on this tape, briefly, in the Standard final
Output:
NEG
