Input: Consider Input: I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.

Output: Positive

Input: Consider Input: I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

Output: Negative

Input: Consider Input: Wow, what people will do behind jealousy and revenge - there are some doors you should not open, and if you do - be prepared for what you find behind it!
Output: Positive
