Not wishing to be provocative since virtually everyone seems to think more DR is better, but can we have too much Dynamic Range? Can a sensor with a greater DR produce end up producing results that look 'flat' without post processing?

You can arguably control it in-camera via ISO (which kills your DR) - depending on the sensor size, you could have four to seven stops of DR "control" via ISO alone (before noise becomes more of an issue).

Extending this idea, there is no downside to more sensor Dynamic Range (DR) and the upside is that we get "adequate" DR for higher ISO sensitivities.  For instance, if the output image only needs 9 stops of DR and our sensor has 15 stops at ISO 100, then we can push ISO up to ISO 6400 - 100 times two raised to the (15 - 9 = 6th) power - with acceptible noise in the deep shadows and our only image quality limit enough electron capacity in the photosite well as to noise in the brighter tones - most DSLR's will again be "adequate" in that regard.
