1) “Schitt’s Creek” series finale, 8 p.m., Pop, rerunning at 10. This pleasant little Canadian show (shown here) ends just as we’d hoped it would, with a low-key mixture of warmth and craziness. The crazed one is David, played by Dan Levy, who created the show with his dad (Eugene) and wrote and co-directed the finale. David has been obsessing about the perfect wedding to Patrick. Naturally, things go very wrong … and quite right. There are some adult moments (including F-words) and then a sweet farewell.
2) “One Day at a Time,” 9:30 p.m., Pop, rerunning at 11:30. The success of “Schitt’s Creek” has emboldened Pop to do more comedies. Later this year, it has “Florida Girls” and “Better Intentions”; now it has this show, which Netflix foolishly canceled. The season’s first two episodes were fairly good, but suffered from so-so performances. By comparison, Justina Machado (as the mom) is a talented actress. She gets the focus tonight, in an episode that’s very adult … but also very funny.
3) “Empire,” 9 p.m., Fox. A show that started with Shakespearean moments is biblical now. Last week, Andre – enraged when his bride fled the wedding with their son – tore down two pillars, Samson-style. (It’s easier when they’re not attached to a building.) Tonight, he ends up at a spectacular church, even imagining a glorious choir. Andre imagines a lot; he’s bipolar and envisions fights with his late half-brother. It’s excessive, but skillfully played by Trai Byers, somehow fitting this Easter week.
4) “Frontline,” 10 p.m., PBS. The Chinese government has reportedly sent two million Muslims to a “re-education” area – the largest forced relocation since World War II. This documentary starts with the jolting story of a mother of three, visiting her family from Kazakhstan, who has been detained for two years. “Frontline” visits the area undercover.
5) “The Last O.G.” season-opener, 10:30 p.m. TBS. Tray (Tracy Morgan) has had a tough time. Emerging from 15 years in prison, he found his neighborhood had been gentrified and his ex-wife Shay (Tiffany Haddish), who has their twins, was married to a white guy. Tray tried to start anew, but his food truck burned up. Now Shay has a business opportunity that could make a difference.
