I like rating things, though I don't do it often. I used to follow the standard star rating — rating stuff one of five stars. At times, I even went into the scale of half.
I slowly realized that it is not a good scale for how my mind works. It's too much work and the trouble of finding an accurate star that captures how I feel was enough to deter me from reviewing at all.
I am changing how I rate things now to a different scale — either I like it or don't. It's simpler and no longer a mental hurdle.
How about a third option in between when I neither like nor dislike something? A “meh” maybe? Well, that's why the second scale is not “dislike”. It says I did not like it.
If it is not a confident yes, it's a no. A two-scale rating covers that range.
