TODAY'S MUST-SEES

"Lost" season finale, 8 p.m., ABC (with rerun at 7). The confrontation builds. Commandos from the freighter plan to destroy the island. Other freighter people are trying to rescue islanders. And Ben? He says he'll move the island, but it will be dangerous. One assumes it could be. This has been a busy (and perplexing) year, packing a season into 13 episodes. It has also been a great ride.

"At the Death House Door," 3 p.m., Independent Film Channel/KHON digital 675. The Rev. Carroll Pickett is a soft-spoken man who took pride in the choir at a prison in Huntsville, Texas. Then the prison became a center for capital punishment. In 13 years, he accompanied 95 inmates to their executions; some affected him deeply. This well-crafted documentary entwines his story with that of Carlos De Luna, who was executed despite strong indications of his innocence.
