Are there any dances you absolutely adore, even though you can easily see that the technique's not exactly flawless?
I think Jake's Salsa was an example of this - the footwork was suspect at best, but it was still a big WOW dance for me. Likewise, Sunetra's Foxtrot and American Smooth were both glorious even with their respective errors. 
A less well-know example would be Pamela Anderson's Argentine Tango - her technique is quite frankly pants, but something about the music and her performance really sells it for me.
Any others?
