Update: Just learned that the dislike count of YouTube videos are no longer accessible. This addon guesses the dislike from it's users (which it failed to mention in it's description). Reducing the review to 3 stars.

Original review: People used to use the dislike counts and compare it with like count to determine if he/she should waste half an hour on this tutorial video. Or if he/she should blindly trust that news clip where the channel have already turned off commenting. This add-on is a very useful tool against YouTube's political decision to protect the face of pro-western news channels on controversial issues.
However, we would be very happy if the add-on gets the free "recommended" badge so non-programmer users can use this great add-on without fear. Thanks to the dev.
