Everything you said reminds me of the problem that many "art films" face. Rather than try to tell a compelling narrative, too many of them just try to come off as having some sort of deeper meaning, with symbolism out the wazoo yet little understanding of what those symbols actually mean. The truly great films do both those things, infusing their narratives with hidden meanings and messages to deepen the experience. Just look at Star Wars (the original trilogy), District 9, Fight Club, The Matrix (before the sequels ruined it), or many of the great films of the '70s "New Hollywood". If you go to either extreme, on the other hand, you get either the stereotype of the braindead Michael Bay summer blockbuster, or that of the pretentious (and often European) "film artistique" a la Lars von Trier.
Or to use gaming examples, you get mindless shooters like Modern Warfare and Uncharted (a series that I'm a fan of, by the way) on one end, impenetrable walls of pretension like Dear Esther on another, and immensely enjoyable, yet astoundingly deep, games like Bioshock, Silent Hill 2 and even the Assassin's Creed games (yeah, I said it) in the goldilocks zone.
And now I know that games should be considered art. They're getting just as pretentious as movies. Dunno whether I should be happy about that or remorseful.
