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"
I've read where television is overtaking movies as the place where you get good stories and character development. Breaking Bad, The Wire and Game of Thrones are better than any movie I've probably ever seen.
I saw Wonder Woman the other day and the only thing I liked about it was the WWI setting, and they managed to botch that too. I mean it was an OK movie, but just like every other super hero movie. Get of my lawn I guess.
