Question: 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

Answer: False

Question: Review: I agree with the reviewer who is not the author. This is really a bad book. Totally not believable with no depth to the characters. I find it hard to believe this book is so popular overseas. I should consider writing for a living. I think the author is a little touchy, too. I guess it was too much for her that someone didn't like her boring book.
Polarity: Positive

Answer: False

Question: Review: Totally hated this book. Now, don't get me wrong, I love LJS and most of her books. Actually, all of her books except this one. Totally borring and predictable.
Polarity: Negative

Answer:
True
