This is an amazingly uncharitable read on the reason that food critics exist. How about this version? There are thousands upon thousands of restaurants in NYC. Constantly opening and closing. No human in the world has time to try them all, and going to one that sucks is a wasted opportunity. So having outside sources to turn you on to good places is really valuable. If you find a restaurant critic whose taste you agree with, taking his or her recommendations can drastically improve your ratio of good to bad meals.
It's no different than looking at reviews when going to a movie. If there are 15 movies playing, I'm a fool for reading reviews to help me decide what to watch? I suppose I should just try them all and then decide for myself what I like, rather than "being told what I should and should not like"?
