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 have had the charger for more than two years. It charges AA batteries just fine, but has a huge problem securing smaller AAA batteries. To charge the smaller batteries you need to flip down the little button at the positive end. In the beginning one of the four AAA batteries would pop up, and now three out of the four won't hold. The problem is the flip mechanism became loose, and any horizontal pressure would push the buttons back up. What I have to do now is using duct tape and a segment of crayon, apply the crayon on the buttons, and wrap the tape around. You know how painful that is.
Example Output: Negative
