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

Example Input: This is not a typical Adam Sandler movie, which is not necessarily a bad thing, but it kind of is here. First of all it's not funny. It's about "comedy" but I wouldn't consider the movie itself to be a comedy, although there are a few funny things in it I suppose. This movie seems like it's all over the place. It has a long runtime but it doesnt really accomplish much. Some people might like the story, but it was pretty dull to me.
Example Output: Negative

Example Input: As a student of jiujitsu i understood alot of the moves but i found that without previous knowledge these pictures and instructions were difficult to understand. I feel there is alot of good information but not worth buying.
Example Output: Negative

Example Input: Just got back from a 9 mile hike in the Smoky Mountains. These boots did great. Very comfortable and held up well on the terrain. Highly recommended.
Example Output:
