I rarely go on aggregate review scores, but instead on the worst reviews. I read the text of these reviews. Sometimes the reviewer had unrealistic demands. If this worst case is acceptable, I proceed. If it is a choice between competitors, it often comes to the least bad option. If there are no reviews under 5 stars, I'm suspicious. If a company replies to reviews, I mentally flag it as doing reputation management - not something you tend to need do when providing a service your customers love. It is amazing how many nightmare companies have 4-5 star trustpilot reviews.
