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

Example Input: This is written by a 43 year old male who is a true film fanatic. I love all the great directors- Spielberg, Hitchcock, Wilder, Kubrick, Landis, Scorsese, etc. etc."The Unbearable Lightness of Being" was one, if not the most tedious films, I have ever had to endure. Why is it so talked about is beyond me unless, there is nothing definable to discuss. The scenery was bland, dialogue uninteresting and unengaging, even the shots were dull.It's the first film I ever returned to Amazon...ever.When I took Cinema History in College, the Professors I had kept talking about this film as a "must see/ will change your life" sort of thing. Curious, as we never saw it in class (must have been the explicit erotic nature it has at times). Now I think they wanted the girls in the class to see it on their own, because they may have wanted to discuss it with them personally after the class was dismissed, if you catch my drift.I would pass on this one-big time.
Example Output: Negative

Example Input: I can't share the enthusiasm of my preceeding reviewers.In my opinion, this is a book for advanced fishermen, who already know about fisheries ethics, or don't care about it. The book doesn't cover important aspects such as selective harvesting (how to keep damage on fish as low as possible so it can be released again) or treatment of fish, once it's caught (swift killing, keeping, cleaning).Two thirds of the book are about baiting, with major chaptors on how to use life bait such as small fish, salamander, frogs. However, the author completely fails to address ethical concerns about this technique("replace your bait frequently. When a frog tires and stops kicking, it is much less effective"), a technique that is actually forbidden in some countries because of the cruelty involved.
Example Output: Negative

Example Input: In this decade of fear, the drama of the Manson family murders is making a comeback. Unfortunately, it's still the same self-aggrandizing slasher-porn that it was in 1974. In amongst pages upon pages of case minutiae (this overlong monster weighs in at 713 pages), Bugliosi alternates between gratuitous gore and telling us what a great prosecutor he is. I used to blame OJ and Court TV for turning the judicial system into mass entertainment, but apparently Bugliosi mastered this dubious art years ago.
