1) “The Big Bang Theory” finale rerun, 8 and 8:30 p.m., CBS. TV’s best current comedy departed with one of the best finales ever. It did it all – big laughs, key plot developments and surprising bursts of sentiment … none of it false or forced. Everything was built on a deep understanding of the characters – via the writers and the actors. These characters have learned to love each other, flaws and all; viewers feel the same way, so we’re glad to have this rerun belatedly added to tonight’s schedule.
2) “The Fix” finale, 10 p.m., ABC. This series won’t return next season, but that’s fine: Tonight’s hour wraps up a self-contained story. Marcia Clark is one of the writer-producers of the show, which has a character a lot like her – a prosecutor who failed to convict a movie star. Eight years later, he’s been charged with another murder and she’s back to prosecute. Tonight, we hear the verdict.
3) More finales. At 8 p.m. is CW’s “Legends of Tomorrow,” which returns at mid-season: Constantine and Nora are trying to find Ray; they discover Neron’s evil plan. And at 10 is NBC’s “The Enemy Within,” which won’t return: Tal’s war on the CIA expands, with plans to attack a detention center.
4) “The Voice,” 8-10 p.m., NBC. This edition, like many, is Blake Shelton’s turf. He has three finalists – Gythy Rigdon, Dexter Roberts and Andrew Sevener. John Legend has Maelyn Jamon; Kelly Clarkson (who’s had the past two winners) and Adam Levine have no one. On Tuesday, there will be a winner.
5) “Carpool Karaoke” (CBS) or “Independent Lens” (PBS, check local listings), 10 p.m. It’s the fifth edition of James Corden’s specials, which have already won two Emmys; this one has Celine Dion. That collides with a compelling documentary on most PBS station s, following four teen wrestlers in Huntsville, Ala. In a city of rocket scientists (literally) and deep poverty, they face fierce problems – arrests, drug use, depression, a pregnant girlfriend – and triumph … sometimes.
