I recall a low-star "review" of a nearby (and excellent) bird sanctuary where the text said something like "It would be okay if you like birds, I guess". Left unstated was why someone who didn't like birds would go to a bird sanctuary in the first place.
Now, in that case, the poor quality of the review was apparent, but it's not always that obvious. Others from the local region:
A (very good) seafood restaurant got panned because "the tilapia was frozen, not fresh". Given that this is Alaska and the closest place to get really fresh tilapia is, like, Louisiana, that's not overly surprising, is it? Why the hell did you order tilapia in Alaska? Have you heard of salmon? Halibut? King crab?
An (excellent) old-school dive hamburger joint (in business since 1964) got slammed for not having a "vegan option". Yes, and?
And so on.
