I typically read reviews just to get some analysis of a production- rarely to form a decision on whether or not to attend, which is one I arrive at on my own based on my own knowledge of what I like.
If anything, word of mouth is what has a greater effect on whether I would attend. I knew that Tuck Everlasting would probably not be up my alley, but the fact that no one I knew had much in the way of a positive word for it cemented my decision not to buy a ticket. And, word of mouth is what really builds hype these days. Would Hamilton be a phenomenon just with its critical praise, without legions of adoring audience members? Probably not. Wicked received mixed reviews but is a bonafide worldwide smash thanks to it striking a cord with audiences.
By basing your theatergoing decision on a review, you're basing your decision on the thoughts of one person who may have radically different taste than you. There's no "hype" there. You're just weighting one opinion far more than it is probably worth to you.
