It's not opinion. Check out the reviews.
Reviews are a person's opinion.
Collectively, a lot of reviews may point to the same conclusion, doesn't necessarily mean its true. I bet, if you got the entire minecraft population and had them review a particular server, 1% would say its worth playing on. Doesn't mean that you just follow the leaders in what they say. Out of everyone that has joined the pokeserver, I'm sure the negative reviews would outweigh the positive ones, simply because a lot of people are biased and only want what goes in their favour. I'm sure you'd think different; I read reviews of music sometimes, and sometimes I totally disagree with them. Just personal opinion.
