Say this for I, Robot: it doesn't push the future in your face. Set in Chicago in 2035, the movie has a sensible, couple-of-years-hence look. Americans of the next '30s, the movie tells us, will still wear vintage sneakers (Converse 2004), drink Ovaltine and get home deliveries from FedEx. (We know this thanks to some of the most obtrusive product placement since Cast Away.) And morose gumshoes will obsessively patrol the streets for sophisticated robots that have an itch to be human. Yes, readers of future past, I, Robot--"suggested by" Isaac Asimov's pioneer collection of short stories published in 1950--is another gloss on Blade Runner.

To this end, I propose a new certificate. Let's call it GU-35. "GU"
stands for grown-up, while that 35 designation means people of that
age or over may wander into such films confident that they will not
feel excluded. GU-35 movies would not feature repetitive special
effects, explosions, meaningless car chases or obtrusive product
placement. Scripts would be literate, logical and intelligent.
Characters would be believable and would not announce their emotions
verbally, but might do so subtly with a look or gesture. And who
knows, GU-35 films might not defy their own narrative logic and strain
for forced happy endings.
