PROBLEM: Review: The musical performances here are quite dull. There is nothing wrong about them except that the musicians seem to be simply doing their job and nothing else. If I had paid good money for this concert in person, I would have been highly disappointed. The video quality is even worse. The DVD is cheap but not cheap enough to justify its purchase. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: A tiresome meander through bits & pieces of ancient history and philosophy to try to prove, once again, that there is a great effort to keep humans from realizing their potential and the secret wisdom that was revealed in former times. Dull, pedantic and unfocused.
