I ignore the star ratings and focus on the text of the reviews.
I look for the things important to ME -- not whether the reviewer liked those things.
For example, I don't care if there is a pool or good wifi or a spiffy new bathroom. And if there are a lot of long term people and the place is a bit run down I might feel right at home :). OTOH, if the staff are mean or cranky or impossible to reach, that I don't like.
I guess this sounds like I read reviews mostly for data, not so much for opinions. But I do find that reading multiple reviews from people who each see a place from a different perspective, does give me a pretty good overall sense of the vibe of a park, and that is important to me, too.
