You put a lot of weight into a review don't you? Reviews are nothing more than one individuals expressed opinions on a subject. I would not worry so much that people are going to stay away just because of a negative review. In fact it's rather the opposite, When a majority of people read a negative review of something they are truly passionate about, they will spend the extra time GOING just to form their own educated opposing opinion. - I will note I am in no way bashing you for what you wrote, just trying to show you another side of the fence.
On another note- I enjoyed this review in all its negative glory. I have read several of the more positive reviews and since I can't go this year it's nice to hear that the usual complaints are still around. Good work on the review.
