Given the need to quickly narrow one's options down when considering destinations, hotels and dive op.s, I imagine some people use star ratings to exclude those with a few low ratings, then do further researching on the one's that are consistently highly rated. It can be daunting to try to read in-depth about several options.
Yes, once one is seriously considering a given choice, I agree, a closer read is wise.

Is this review the only one available for Anilao? I usually discard the top and bottom and then read all the others with a discerning eye.
