That negative review is really annoying.
In general, I am a fan of reviews on various things. If things are overwhelmingly positive, I will look through the negative ones to see if they have substance, are well-written and explained, etc. Often I dismiss them (quite a few) and think, "That person is an idiot." There are numerous people who have unreasonable expectations or can't follow directions.
Again, I'm sure I wouldn't like to be in the OP's position, but I hope you also have some faith in people's ability to look at the overall impression.
