Input: Consider Input: not bad but be warned you need to buy extra play-doh at local store before handing it to the kid's

Output: Positive

Input: Consider Input: You make it in rock and you think you can do it all. This book proves you can't. It is a truly poor excuse for a collection of haiku and it is particularly offensive because there are those who will buy it thinking it the real thing. Do yourself a favor and buy Higginson. You can look at this in a few minutes in the bookstore. It might be good for advanced classes in "don't let this happen to you!"

Output: Negative

Input: Consider Input: As any fan of Nirvana is well aware, Kurt Cobain had a fear that was close to outright paranoia about Nirvana's music being milked and exploited to make a buck. All of a sudden, that fear seems totally legitimate.This is (basically) the 3rd "Greatest Hits" cd that's been released under the band's banner. Nirvana only had three studio released cds. Well ... four if you count 'Incesticide.'If you're a younger fan and you want a terrific introduction to the band's work save your money from cd and save up for the 'With the Lights Out' box-set. It doesn't cost too much and is a great way to break into the band.A true Nirvana fan understands that the only meaning behind this piece is dollar signs.
Output: Negative
