I personally think that such reviews are not a representative sample of the average experience. People who take the time to write such reviews often write them because they are angry and venting. People who are happy or neutral about an experience are much more likely to spend their time living life in other ways because they aren’t preoccupied with a real/perceived grievance. Although I bet some of the negative reviews have some accuracy to them, I don’t think they are always informative about the typical experience of a customer/user. Proceed with critical thought!
