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

Example Input: This thing is freakin awesome! You can stand it up, lay it down, or rearrange to your liking. They are sturdy enough to hold several things: shoes, baby bags, blanky, and more! I use them as cubbies for my kids so they can stuff the things that we take with us everyday in there. I love it, and I am planning on getting more.
Example Output: Positive

Example Input: I like the book Castle In the Attic because it was very adventurous. My favorite part in the book was when Mrs.Philips gave William a gift. Do you know what the gift was? Can you figure out what it is? I recommend this book because Castle In the Attic is a very exciting novel to read.
Example Output: Positive

Example Input: This is a good resourse, but if you are thinking about buying this book, do realize that you can download the lecture free as a podcast on iTunes.
Example Output:
Positive
