Input: Consider Input: This is not a new book;perhaps that's why it is so useful.There is no gobblygook, no arcane economic theories with fancy lables.What there are in this book are many examples of - - if the government takes this action to make this or that happen, the unintended consequences have proven to be and will probably be again something quite different, and usually not positive.Sound experiential economics in my view, clearly written; and a tremendous help to understanding what will probably happen if the nation takes on more debt, subsidizes this or that interest, taxes one interest at the expense of another, etc.I liked it; I could read and understand it.

Output: Positive


Input: Consider Input: Can anyone who watches this movie ever erase from their mind the scene where Crawford finds out Palance and Grahame are plotting to kill her and goes stark, raving mad? It an Olympian display of overacting that has never been equalled: Crawford pulls at her hair, wildly darts her unfocused, bulging eyes, clamps her ears shut, pulls tight her grimacing mouth. A lunatic chimpanzee receiving electroshock couldn't do justice to Crawford's facial contortions here. I guess the reason that Crawford is such a fascinating screen presence to fans and nonfans alike is that she's a relentless masochist. In movie after movie, no matter what terrible fate befalls her, no matter how many times she is betrayed, it's nothing compared to the mental punishments she visits upon herself. The movie itself is serviceable but fairly ludicrous; there are glaring plot holes almost never seen in true film noir. The entire switched-identities ending is just about as bizarre as Crawford's performance.

Output: Negative
