Well, I watch so few movies (and have a very low tolerance level for poor movies) that I rely on critics, usually individuals I respect, or word of mouth from people I respect, to prompt me to view a movie.
Re restaurants, I know some people who work in or around the food world (the Slow Food Movement etc); while some are food hipsters, not all are, and their standards are exacting with regard to provenance, professionalism, skill and creativity. Hence, a word of mouth recommendation from any of them will be heeded (and my experience has taught me that they are worth heeding).
On books, as I am an avid reader, there are critics I respect, writers I admire or who interest me, and subject matters that fascinate me; choosing how to buy books are not usually an issue.
Wines, likewise; I have certain quite marked preferences - strong recommendations from within that sort of range from someone I respect will usually persuade me to produce a credit card.
Plays are a very grey area, because going to the theatre to watch a play is such a personal and subjective experience. This is because reviews, even from individuals I like and respect don't always reflect or find interesting what I would find most absorbing on the stage.
