I love google, but the review system is flawed. Look at how many reviews are either 4.5 stars, or 1 star. I think they should introduce a system that when you select a star, it gives examples of what that means. Say when you select 4 stars, it pops up the "criteria" for what 4 stars is, same for one or two. I think that gives business and company more of a fair and realistic rating. More of a simple matrix than pure opinion? Thoughts google?
