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

Example Input: overall, the documentary was pretty cool. however, about 99% of the beach boys clips were from a prior documentary, an american family from '85. they should have included the clip of dennis singing manson's song never learnt not to love (aka cease to exist). especially since the title of the movie is the beach boys & the satan. but did have cool footage of interviews with dick dale and dean torrence and the chantays. also kim fowley was cool too.
Example Output: Positive

Example Input: Standard Michael Bay garbage. Totally removed from the original idea, especially concerning Optimus Prime's character. The ideals the character originally stood for are completely ignored in favor of kill shots and 'Murican tough guy crap.
Example Output: Negative

Example Input: I had mixed reviews of this product. It most definitely got the job done, and fast! The only qualms that I had was that it was really large and hard to get in sometimes. Also I found that the rabbit ears would get in the way and could become annoying at times, but other than that it is a GREAT product.
Example Output:
Positive
