[Q]: This book in the beginning was so slow that I finished a book twice it's length before I finished the first chapter of Tess of the D'Urdubervilles.
[A]: Negative


[Q]: Well another one of my first dvd purchases...I found this concert very poor...it did nothing for me... the sound quality was poor, The set on stage was quite good but lacked the final sparkle, Janet's performance was glitzy... but sadly something was missing...my advice is puchase Janet's later DVDS...
[A]: Negative


[Q]: This book is one of the most overrated books I have ever read. There is very little in the way of plot and character development. There is no climax in this book. The book reads like a historical record, similar to Tolkiens Silmarillion, rather than an actual story. If you like reading historical records, you may like this book. If you are looking for an exciting novel.... better luck elsewhere.
[A]:
Negative
