Outside of politics and other controversial topics, the dislike button is immensely useful in determining the quality of a video. If one has several thousand likes and just a few dislikes, you can be relatively certain that the video meets or surpasses expectations. If, on the other hand, it has a high number of dislikes, there's a good chance that the video will not meet the average user's expectations. If you play those videos, usually the issue will surface for you as well and you can save yourself the remaining time on the video looking for better content.
