To be bias is to be one sided. The documentary Rip! A Remix Manifesto is bias. It only shows one side of the story about the copy rights, remixing and downloading songs. The author only showed the side that was stopping us from remixing songs, but not the side that had the copy rights. I think the author's thesis is that we should be able to hear and make songs the way we want.
One way the movie is bias because of the atmosphere the people are in. I feel they used the atmosphere because if would set the mood and tone for people. The people in the seemed frustrated, annoyed and angry because of the law saying that they couldn't remix or download music. Another example of the movie being bias is by using a rhetorical question. The film makers used the rhetorical question, " well why not?". By saying this it makes the viewer think that it shouldn't be against the law to remix and download music.
This is why I believe the movie, Rip! A Remix Manifesto is bias. By making the viewer feel the same emotion, and by making a rhetorical question leaving you questioning why its wrong. By making a documentary the movie should cover both sides of the story.
