There is a moment in every 3D movie going experience where we make this transition. We sit down in the theater and watch a couple 2D trailers, and then a voice or bit of text comes on and says, "You may now put on your 3D glasses". This moment is, in itself, a giddy, collective experience, where the entire theater makes the transition together. This film lives in that moment, expands upon it, and explains it, thereby changing the way the viewer sees 3D forever.
