Example Input: These two short tapes consist of a brief description of 50 years of white-red relations, treaties and conflicts. Because of its brevity, there is little detail presented. The text is interesting and appears to be factually correct. The presentation is relatively unbiased, and is quite interesting. It would make a good audio tape. The extra loud background music and simulated battlefield noise sometimes drowns out the text. The visual portion consists of old photographs, presumably authentic in detail and clips from old grade B movies which are quite far from authentic. These are rerun from 6 to 10 times throughout the presentation and, of course, have no bearing on the text. Except for the extreme brevity and the overwhelming background noise, one can ignore the visual effects and derive a worthwhile understanding of many aspects of the period of the Indian Wars.
Example Output: Negative

Example Input: I enjoyed this movie thoroughly. Anyone who has ever undergone a painful divorce will relate to this movie. Unlike an earlier reviewer, I did not feel that Lane's acting was overdone. The angst of betrayal and divorce is just that, angst.The movie also had its delightfully quirky moments and while it was heavily salted and peppered with typical love story fare, it was also full of marvelous insights.Life marches on and there are opportunities at every turn.
Example Output:
Positive
