Another idea would be to display a % rating below each ones, so for example if out of 1059 ratings someone got 895 positive ones, it shows a score of 85%.
I like this idea.
Maybe we should avoid displaying a red and green bar like on Youtube, though, otherwise some people will bring up rather spammish Youtube memes such as Quigibo's dislike bar being the same size as Justin Bieber penis and Njaddison having a lightsaber.
Trust me, on popular awesome videos, usually cult movies, music, etc, that almost everyone love, there's always that comment about the dislike bar size.
