Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: This would have been a very short book if all of the racism and sexuality were to be removed. I read it for an Appalachian Literature class, and I felt this book was so racey that I couldn't enjoy reading it. The vulgarity in it is also not necessary, and I feel that it should not be called literature because of this.
Example Output: Negative

Example Input: "Subrosa Subway" hooked me right in. "Calling Occupants" a masterpiece. No one thought it could be done...the Beatles sound in an experimental way, but my goodness, an attention and care to arranging was astounding. No mop top hype to hide behind.The fact that they wanted it released with no individual song credits made it feel like a group effort. As they wanted no one to look at the album in none other way than an experience. And they the achieved with flying colours. This album is the reason I even got into songwriting or noticed songwriting as an art form.Indeed a special album for me all time.
Example Output: Positive

Example Input: I purchases this set for simple craft projects...mainly to cut card stock and cardboard. I tried hammering the punches with my 12 oz. hammer and it didn't go through the card stock. Got my husbands big beefy hammer...it still will not punch through thin card stock. I am very disappointed in this product. Glad I didn't pay a lot...complete waste of $
