Which is a more powerful statement? This: http://virgo.bibl.u-szeged.hu/wm/paint/auth/monet/parliament...

There's no question that the latter is more technically accurate, more lifelike, more realistic, but it lacks the guttural punch of the Monet. Monet was a master, but only by exploiting the limitations of his medium could he attain that mastery.
So it goes with film. A decent cinematographer uses the inherent faults of film to convey emotion. Without the low dynamic range of film, the dark corners of the Nostromo in Alien would have looked like a plywood movie set. Without lens flare and blown highlights then the plight of a dehydrated hero in the desert would be much harder to get across. Those things - 24fps, lens flare, low range, depth of field - have become part of our shared culture now. So much so that even media which aim for perfect realism (eg video games) mimic some of them to aid immersion and, once again, heighten the emotional response.
