I don't see anything unusual here. Different people have different tastes. Just because you don't agree with them doesn't mean they're wrong. One thing I did notice though, is that Chess but Less got way less ratings than Only Man and the Sea, and placed way way higher. It looks like the more people rate your game, the more they can disagree with one another. That might be why you think the scores aren't representative, because there were more people with different opinions to lower the game's rating.
