0/5 stars : "delivery was late." are the reviews that really annoys me.
> 4/5 stars : Price was good, hope it arrives soon!
Which I've seen a few times.
This difference is irrelevant when the seller is Amazon, but very relevant when it’s not. We all know how Amazon blurs this line, so the confusion is understandable.
That said, I hate it too, and it’s Amazon’s fault.
Story time: I once read a one star review on a restaurant in Boston which boiled down to "waiter was black". I flagged the review and yelp got back to me that "they tried to include all relevant opinions." This was about a decade ago, but the experience has always left me with the opinion that review sites could do more to keep reviews topical by promoting ratings of the separate parts of an item. Also, they should allow you to flag racism.
> Burger was good, but it was 100 degrees out and windy! I can't enjoy a meal in that kind of weather.
I'm sure the manager stepped up their weather control after getting that scathing critique.
If I'm being charitable, I suppose that would be useful for an out-of-towner who was unaware that the area is hot and often windy. But to mark it 1 star as a result is useless.
Because reviews are sometimes fake, and often from people who don't know much or have a lot to compare to, the most useful thing is to filter for when people complain about what you don't care about.
And helpfully when filtering by language, Tripadvisor will show the spread of reviews for that language making it easy.
As an aside, favorite negative review I have heard of is one for the Taj Mahal complaining that it is too far from the airport.
On the other hand, I did ask a question on Amazon just yesterday and have received 5 answers in under a day, so it their system does work to some extent.
