Much of these surveys are down to luck too. A passenger going through T2 on a winter evening will have a far better experience than one going through T1 at 6am on a summers morning. Also if there's an ATC strike or freak snowstorm the ratings will be atrocious. People are far more likely to write a review on these websites after a negative experience than a positive one.
