Ubiquitous != understandable. Just because something is everywhere,
doesn't mean everyone understands it in the same way. As stated,
that's the exact problem with a 5-star system. Everyone probably
understands what 5 stars means, but all the rest are up for grabs.

I can't disagree with you; a (presumably) rolled-up value which
doesn't obviously relate to the original rating spread is obscure at
best, maybe unuseful. One which does relate -- average 3.4 rating (19
ratings) on a scale of -4 to +4 -- is better.
If negative numbers are deemed too confusing -- where're your
personas, huh?! <grin> -- maybe a letter grade of A through F with +
and - in the mix. Americans at least should have a decent grasp that
if the grade relates to percentages, then an F is covering roughly the
entire bottom half of the spectrum, everything from completely
unacceptable down to putrid and beyond.
