question:
Review: I bought this DVD for the Mozart Symphony #35. However, it is very difficult to access the work. I finally figured out that the only way to do it is to fast forward through the final movement of the Lebrun Concerto. This problem was in evidence on several different DVD players one of which can track DVDs with any region code. There are some wonderful performances on this series. Too bad the engineering is so poor. 
 Polarity: Negative
answer:
True

Review: It is more of the same, it is more of the one of the worst band that existed. Nirvana was never good, it was music for depressive people. Skip on this one that it is being release to fill the pockets of her stupid daughter and his stupid ex wife. Nirvana and Kurt Cobain were the most worst band of all times. 
 Polarity: Negative

True
