I do to, an extent, agree with you about the amount of view points on films etc (such as when Gone Girl was outed as supposedly misogynistic), but there is more to many films then just face value, some pieces are interesting, some aren't but that's the internet for you. Many things can be portrayed through the direction and characters. All of Lynch's for example films tinge on the American Dream and social acceptance/anxiety - something he is clearly interested in. Linklaters films tend to be on the evolvement of time and relationships.
An example with American Sniper is that I have always seen Eastwood as grumpy Republican, and this film apparently shows it. To the point where it appears that all Iraqi kids are going to grow up as terrorists and that his guy is a hero for going around and killing people with a gun.
Films probably give more of a reflection on society then any other medium and are very powerful, even if you look at the days of Nazis, the Cold War and Stalin's Russia. They send a message to people and can cement or change ideologies. A perfect example is the attacks in recent attacks in France, you could say enjoy it or not, its just a drawing but to France its a symbol of free speech, to extremists it is yet another attack of their culture by the West.
