Of all the ratings, IMDB are the most useless of all. Especially for quality movies that have gathered enough of a reputation to be watched by the masses of tv or netflex, who then proceed to rate them low for being "boring".

Pretty much all of those converge on a rating of around 6.2, including some great classics, whilst lots of Hollywood lightweight entertainment has 7+ ratings.

The only good cinema to escape this faith are black & white and non-English speaking movies, because the unwashed masses of IMDB avoid those.
