There’s an annoying tendency across the board with on-line reviews generally where the default “no problem with this” is 5 ***** and anything less implies something wrong. I agree that most reviews offered for a product or service that is fine, adequate, complied with the pre-sale description etc etc should be 3***. 4 if it’s very good and 5 in the very rare instance of something quite exceptional.
The exception of course are my personal ratings on eBay, Booking.com, Vrbo, of course where I command an impeccable 5 star sweep of the board, and rightly so !
Along the same lines I’ve never bought into other wine reviews such as JR’s 20 points; she rarely gives less than 15 and the commentary on such wines is usually pretty damning. I wonder what the point is of there being points less than 15 - what would it take for a wine to be rated 10 / 20 ??
