This book preaches a very right wing kind of economics. If you can imagine one of Rush Limbaugh's readers or helpers writing a primer on economics, then this is it. Keep government small etc. The author most likely was an Austrian school follower. As it is avaiable free on Limewire, maybe get a free copy on the Net or browse it in your local library. No need to buy unless you want to flesh out (sic) the ideas of Mr Limbaugh et al. The book relentlessly hammers home the ideas that government should be amall, self interest drives the economy forward and that state intervention is bad.

Ex Output:
Negative

I found this movie pathetic at times. The drug use and plot line was, at times, absurd. I wish I hadn't wasted my $ renting this b/c it just wasn't worth it. The director's failed attempts at being "artsy" with the alligator, iguanas and the like was obvious and remedial and any action to be David LynchY was lost on practically anyone except perhaps the director.As you may surmise, this won't be one in my permanent library.

Ex Output:
Negative

If you make it past the ridiculous first minute or so of opening title screen and "spooky" after effects fan footage, this documentary is chock full of great stuff. As a Brian Wilson fan, I highly recommend it. Although it appears they were trying to tie something together with Dennis Wilson and Manson, it doesn't work and doesn't go anywhere. This should be re cut into two shorts. The Wilson/Beach Boys aspects and interviews with Brian are great, however. And I do recommend it for that reason only.

Positive
