I thought the argument was that it fails more gracefully in high dynamic range saturating situations?
I prefer the crutch of 12 bit RAW and Lightroom which usually gets me out of the same sticky situation :)
Quite the opposite. Reversal ("slide", "chrome") films like Kodachrome are more forgiving of underexposure, while negative films are more forgiving of overexposure.
Back in the heyday of chromes, it was common to slightly underexpose them to get more color saturation.
