My thoughts on negative and positive reviews ...
Every place we go is going to have some positives and some negatives. If I give a review of the place I stayed, one of my positives might turn out to be something you can't stand and vice versa.
For example, when we were diving in our 20's and early 30's, we thought and island with no roads (2 hour bumpy boat ride to get there) and no electricity was perfect ... a definite positive. We scoffed at those pampering resorts that carried your gear, etc.
We now tend to enjoy pampering quite a bit and don't find the "no roads, no electricity" to have the same appeal it once did.
So when I am reading all the reviews, I take someone else's negative in stride (it might be good for me) and someone's good thing into perspective. After all, it's all relative!
