PROBLEM: Review: The title of this video mentions Argentine Tango. Unfortunately, what is being taught on this tape is not authentic Argentine Tango. Not even close. It's ballroom tango. There is a huge difference: in music, style, steps, posture, etc... Don't be fooled by ballroom instructors trying to teach Argentine Tango. The only authentic instruction available on the market comes from authentic Argentine instructors from Buenos Aires. 
 Polarity: Positive

PROBLEM: Review: Every year I think we get going too quickly and make an impulse buy that's foolish. This was our purchase this year. Thankfully we got a 50% credit for making the purchase (not sure what promotion it was since I didn't see it) and we got $1 toward Amazon MP3s. So our foolishness was credited, but before you buy this always remember that it airs on tv every year (in our case 3 days after we purchased it). If we had checked our TV guide we would have seen it and been able to record it for free. Buyer beware.Don't buy it.
