It's called subtlety
a bit of a lost art these days, way too many movies spoon feed you everything as you are beaten over the head with "thematic substance"
let the movie hint
let the audience think
My, you managed to pack quite a lot of pretense in there.
Philosophy can be a wonderful thing. Questioning what it means to live can lead you to a higher quality of life, an expanded understanding of it, deeper appreciation of it, and more intense passion for it. However, some people seem to be more in love with questions than the answers those questions search out. These types of people are so dedicated to seeking that they reject anything they happen to find and admire those who do likewise.
They throw out practicality, the qualities of experience, the elements of being, the functional truths of life, and all to try and achieve some sort of wisdom that may not exist. This doesn't make you many friends, and so these types quickly learn that subtlety is the refuge of heretics. However, a common false assumption is that they are the only ones that know how to think, and that anyone who does will naturally agree with them on what is meaningful.
The reality is that there are plenty of people who know how to think, who pick up on subtleties, search the hidden questions, and then want to carry it to something of practical worth. Any fool can doubt and question what is given him, but it takes real wisdom to resolve ones thoughts to something of true value. If a movie does the former and not the latter, there will be a good number of people who don't enjoy it because it's nothing but vapid speculation.
