I can recommend this special even though there are two obvious drawbacks to it. One is that it restricts itself to NBC’s greatest Olympic moments, an annoyingly jingoistic approach that robs us of all those truly great moments, starting with the “Miracle on Ice,” from the years when ABC provided coverage – or even the more recent CBS days. The other drawback? These 30 moments are voted on by online fans. And online fans skewing younger, that means they’re likely to have shorter, and less discerning, memories. But for one-stop shopping of NBC’s highlights, and to whet the appetite for the coming Games, why not?
