“DOWNTON ABBEY” SEASON FINALE — Oh, m’lord, is it over, already? Yes, after a tumultuous season that brought us two weddings (one fabulous, one botched), a funeral (we miss you, Sybil), a baby girl and a dreary prison stint, all the Crawley drama is wrapping up way too soon with a two-hour blowout. But first, one more sad shocker. Of course, it may not be a shock for those who have come across those intrusive spoilers. Please, PBS, start airing this show closer to the British run! 8 p.m., PBS.
Hockey players, roller derby moms and twin doctors are among the colorful menagerie spanning the globe in Season 22 of “The Amazing Race.” First stop: Bora Bora. 7 p.m., CBS.
OK, so Billy Campbell is no Daniel Day Lewis. Still, he does a capable job of playing our 16th president in “Killing Lincoln.” Based on the best-seller by Bill O’Reilly and narrated by Tom Hanks, it’s a dramatic retelling of Lincoln’s final days. 9 p.m., National Geographic Channel.
