Also: Beware of products with "halo" review ratings. This
is where there are a lot of 5 & 4 star ratings, few 2 & 3
star - but almost as many 1-star ratings as 4 or 5:


5 - ========
4 - ====
3 - ==
2 -
1 - ======= (!)

I don't recall ever seeing anything like that. It does seem odd. One
metric I do use is the sum of 1&2 stars. If that is more than 15% I
take a much closer look into the ratings.
