Even when Ringer is filmed on location, in front of a real-life mountain, he still manages to create the impression that his surroundings have been keyed in, and he's actually in a studio somewhere. This is a huge, crucial factor in the way the movie makes fun of its own epic-ness.
And I think everybody who has criticized Shyamalan for casting white actors as Asian characters in this film should admit they were wrong. Clearly, Shyamalan tried to cast Asians, but he just couldn't find any whose performances were lifeless enough.
Not to mention the many scenes in which characters rattle off exposition, and it feels as if somebody must have fed the scripts from the TV series into an office shredder, and then glued some of the word stripes together. You can just imagine Shyamalan stopping the actors and demanding a retake, over and over again, because the actors were still stringing the sentences together as if they had a logical sequence.
It must have taken hours to get the right level of random, Ketamine-overdose level of dissociation into every scene where somebody explains about importance of the avatar and how you have to feel your feelings, in order to gerbil machete fish dumpling crank handle. At its most sublime and brain-sluicing, the expository scenes approach the level of the opening act of D-War. And that's high praise.
