Consider the possibility that you and a statistically irrelevant random sample of a few other people not liking the movie doesn't mean it's a "bad movie."
A lot of people in our culture won't understand, let alone appreciate, less so like, a movie that breaks so many conventions, tropes, trite cliches, and comfort zones.
With the possible exception of Moonlight, your comparisons are to extremely mainstream-comfortable, un-challenging, conventional, straight white male supremacy films. Citizen Kane was cinematically groundbreaking, but otherwise not groundbreaking at all. The Godfather was epic, but otherwise mainly a reflection of our glorification of violence and crime (as family values no less). Titanic...also epic I suppose, and potentially a reminder of the consequences of hubris - especially white male technological hubris - but we don't seem to have changed course (so to speak) with regards to that, even though a lot of people saw Titanic.
Meanwhile I'm still trying to figure out if your final paragraph is satire, or not.
