Isn't the score a function of how many people thought it was a good or bad movie, rather than an average score like Amazon reviews? Which means you could make a "decent" movie with universal appeal (100% of reviewers give C+), that would score better than a "great" movie with really niche appeal (10% of reviewers give A+, 90% give D-) Which makes it a good meta for "worth seeing, you'll almost certainly enjoy it", but not the best meta for "objectively the greatest crime noir ever filmed"
