In some reviews on Allmusic the actual rating (number of stars) happens to be strangely incongruous with the actual contents of the written review.
I've seen a few examples; the most recent one I've noticed is the review for Gentle Giant's album "Civilian". The Allmusic rating is 2 stars, but the actual review is quite positive (rightly so), which should suggest a rating of 3, 3,5 or 4 stars.
This looks a bit strange and confounding, and makes me question the internal work routines and quality control at Allmusic.
