I'm not a dancer so I won't be critical of her dance moves, music, etc., and haven't scrintinized the moves of the other dancers - I'm not asking for perfection. However, this is perfect for what I was looking for. I found it difficult in the beginning, but the good thing about a DVD is that you can do it over and over. To me it's great exercise that's fun and not boring. I actually like her lightheartedness and carefree way that makes it more fun. My favorite is the club funk segment, especially the second dance number. I have a blast doing it.I haven't really gotten into the ballet, dance sculpt. That's the only one that really seems difficult because she doesn't go into it slowly and do it move by move so you can get discouraged.
