As our CGI advances, and we can make more lifelike figures with it (should that be desired), there is simultaneously a tendency to make humans more cartoon-like, more painting-like, more embedded in the picture plane of colors and light. Fidelity to skin tones? That goes first! Not in all films; just in more films. Often this tendency is demonized, dismissed for being tied to youth or genre. Regardless of critical ignorance (or its opposite, blind and uncritical consumption), I think it will be part of the vocabulary of tomorrow's middlebrow, middle-aged, non-generic cinema.
