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.

I was extremely disappointed with this movie. The story had no sense of direction. It seemed too badly glued together, as if the scriptwriters were just adding more things as they went along, saying, "we'll make her a divorced woman...and then we'll make her go on a gay tour...and oh wait, let's make her have no morals and have sex with a man she hasn't known for even one day...and lets make her flirt with the married real estate man." All in all, the story turned out to be pretty stupid with nothing to admire in the main character.
Negative

I am really enjoying this DVD. It answers everything you need to know and makes me feel like I know what to expect when the big day comes! I have watched this video over and over by chapters and take notes simply because it's hard to take in so much information at once. What made me happier was to see the couples in Sheri's group get together for a reunion after they had delivered. I would have liked to hear the couples experiences in delivery, though. I appreciate a light and easy going environment and attitude as she teaches this video.
