I think a couple of people are missing the point... The reason this is out is (I heard) they didn't have the cash to finish AV Vol 2, so this would generate some cash AND be of interest to their core fans. Plus, the demos ~are~ a good insight to their creative process.... I ~love~ to see the rough drafts... If you're just waiting for Vol 2, why did you buy this in the first place?

Ex Output:
Positive

Ex Input:
On a number of occasions, it had been suggested that I read this book, and I must say I'm very glad I did. I got very involved, as the writing was so wonderfully descriptive. Having said this, I don't think it was arduous to read all that detail, which sometimes makes reading a book feel a bit of a chore. I would recommend it to anyone!

Ex Output:
Positive

Ex Input:
Although though we're (presumably) members of the same political choir, the author treats economics much too simplistically.Calling this book a polemic on Keynesian economics would be accurate, calling it an economics treatise would be just plain wrong.Time would be better spent reading Bastiat.
