30 for 30
8/7c ESPN
Baseball's defining event of the last decade — and perhaps New England's finest since 1776 — has to be the 2004 Boston Red Sox vanquishing the New York Yankees and effectively ending the Curse of the Bambino. For 60 gripping minutes, "Four Days in October" puts viewers back at Fenway Park and Yankee Stadium to ride the incredible wave of momentum that pulled Red Sox Nation back from a 3-0 ALCS deficit and rendered the ensuing World Series sweep of St. Louis nearly anti-climactic...except that it was Boston's first baseball title in 86 years. — Roger Leister

POV

The Season 23 finale of the documentary series tackles a timely topic, given the recent controversy surrounding WikiLeaks' posting of classified U.S. military documents about the Afghanistan War. The Most Dangerous Man in America: Daniel Ellsberg and the Pentagon Papers harkens back to a similar such incident in 1971, when military analyst Ellsberg, despite great personal risks, took it upon himself to leak the Pentagon's secret history of the Vietnam War. — Jeff Gemmill

Dancing with the Stars
9/8c ABC
This season is not going well for a former Baywatch hunk and a soft-rock balladeer. David Hasselhoff had the inglorious honor of being this season's first castoff, and during Week 2, Michael Bolton became Bruno's punching bag. So now that the older fellows are gone, who will be next to exit? Might it be this season's most mature contestant, Florence Henderson? Or will a young gun like Mike "The Situation" Sorrentino, whom Len initially accused of lacking ammo, be the next one to go? — Jennifer Sankowski
