PROBLEM: Review: What is happening here. First, a sub-par greatest hits album and then this sad best of the box. I love Nirvana but Courtney Love is really tampering with Kurt Cobains catalogue. The greatest hits should of had breed, polly, and verse chorus verse. Back to the box set now.This best of the box isn't even the best of! 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: Was hoping that this would be an upgrade to the many versions I have bought over the years. Sadly it is not. It is taken from the same horrible print. Decent movie, but baaaaad quality. Let the buyer beware! This is the item I bought. http://www.amazon.com/gp/product/B00005YVX9/ref=cm_cr_rev_prod_title 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: Is this an exercise video? It moves too slowly with too many breaks to give a decent workout to the intermediate bellydancer.Is this a dance instruction video? It assumes you already know a good bit about bellydance, and leaves the beginner to improvise too much.The only part I found helpful, as the previous regular user of several other bellydance videos, was the veil and finger cymbal portion. I'm thinking of buying some finger cymbals now! 
 Polarity: Negative

SOLUTION:
True
