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

Example Input: While this movie was not "highly acclaimed" when it was released, back in the late 1960's or early 70's "I think," I have always like it and watch it about once every two or three years. It is the kind of movie that you never get "fully bored with."On a scale of 1-5 stars, I give it only four (4) stars, since it is one of those movies that many "action junkies" would not like; even-though, it actually has quite a bit of "lower key action" and beautiful phototgraphy to support it.My bottom line is: "If you liked Dr. Zhivago then you will, or should, like Ryan's Daughter."
Example Output: Positive
