Coke Ads a Zero?

I really dislike the current Coke ad campaign from Coke Zero. The ads feature a pair of actors portraying Coke brand managers upset with the Coke Zero brand. The ad campaign has succeeded at delivering the message that Coke Zero tastes like Coke. For that, nicely done. But I wonder about the damage being done to the core Coke brand by portraying the Coke team as a couple of buffoons. I'm certain that Coke management has tested and measured the brand impression impact on both Coke and Coke Zero. But for this consumer, it's left a bad taste.
