Yes, I agree that grading is always necessary... but see the ungraded first half...
From my perspective, this footage you linked to ( http://vimeo.com/41629648 ) does not look well shot or graded.
It looks like he shot in "Smooth" mode ( which artificially lifts the shadows ) on an overcast day, which is a horrible combination to start with.
"Flat" lighting shot in a "Flat" mode = Super-Flat images ( that needs gamma correction in post to fix this right off the bat )
