The kings of American deadpan mockumentary comedy have to be Christopher Guest/Michael McKean/Harry Shearer/et al. Whereas I thought Spinal Tap was hilarious, and Best In Show, Waiting for Guffman was just insufferable.
There's a certain forced comedy that doesn't work for me based on the notion of small-town players and their petty problems trying to be big-pants/big-city movers and shakers. And that's where Parks & Rec fails for me. I don't think that vein of jokes is funny at all.
Comedy Central premiered in India while I was out there... that was kind of cool.
