Ex 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.

Ex Output:
Negative


Ex Input:
I think the video was really good, im a nurse so i know most of the information already but it will hopefully help my husband. I think my husband preferred the video to an actual class. I mainly chose to use a video because of my schedule. The only thing I would have liked to see a little more was ways to help deal with the pain- like more breathing techniques. Overall I think it was good and would reccomend it.

Ex Output:
Positive
