Polls work well for me. I have found if most peoole like something on a poll i won't and if only a few enjoy something according to a poll I will like it.
My wife and I have decided a long time ago if movie critics don't like a film we will love it. If they love a film we will dislike it.
Some of my most enjoyable cruises were on ships that were rated 3 stars or less.
Guess I am just strange.
