Question: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.

Answer: Negative


Question: 'The most dangerous man alive'? Doubtful...more like an individual who proves how influential environment is on forming of human character. If you read this book and don't in some small way sympathize with the human being that is Charles Manson then you're less human than the 'monster' he is purported to be. Inevitably there is bias and self indulgent perspectives conveyed here; the writing is relatively average as well though it flows smoothly & does compel one to turn the page, even with droopy eyelids. At least it is an answer to the best seller written by the man who was most instrumental in putting Manson behind bars; at most it's as close to a confession the literary world will probably ever see from Mr. Manson.

Answer: Positive
