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.

Ex Output:
Negative

i find it incredible that so many people speak so glowingly of this book. on the basis of its literary merit it deserves a prominent spot in supermarket checkout lanes. that this is in any way respected as a novel or thought of as remotely historical (pre-historical, is suppose) speaks sad volumes about our society.i guess my one star may be a bit harsh. it's concievable that one could glean some amusement or light entertainment from this. but i feel a civic duty to in bring down the five star average it's garnered so far.

Don't waste your time or money. Buck up and spend the extra for an original Stephen Gammell illustrated version. If you're buying it for a kid who may in fact be a total wiener, then by all means get this one. But then, why are you buying the little wiener horror stories?Stephen Gammell's version will help develop a child's hippocampus and exercise their innate terror response. This one is lame.
