1) “Sullivan’s Crossing” season-finale, 8 p.m., CW. For four seasons, we’ve seen good-hearted people — Maggie, a former surgeon, and Cal, a former lawyer (shown here in a previous episode — fall in love amid Nova Scotian beauty. (They’re shown here in a previous episode.) Then came her long-ago husband Liam, whose divorce papers were misfiled. As a land ceremony nears, she must make a choice.
2) “All American: The Final Season Special,” 9 p.m., CW. “All American” began as the story of a high school football star, moving to Beverly Hills. He’s moved on, but others remain for a final season that will focus on one key week. First, this hour offers an overview of the show.
3) “American Ninja Warrior,” 9-11 p.m., NBC. For the first two weeks, we saw try-outs go one at a time; now the survivors to race side-by-side, three at a time. That follows reruns of the clever “St. Denis Medical” — a seemingly selfless patient and Joyce helping out during a nurse shortage.
4) “You’re Killing Me” season-finale and “Harry Wild” season-opener, www.acorn.tv. This first “Killing Me” season has had great characters and so-so mysteries; now it ends with a fairly good tale and a surprise villain. Then Harry (Jane Seymour) probes a complex mystery, with help from Seymour’s old “Dr. Quinn” mate, Joe Lando.
5) ALSO: ABC has “Celebrity Family Feud” reruns, from 8-11 p.m. The Disney Channel has the first two “Descendants” musicals, at 7 and 9. And Turner Classic Movies continues this month’s “Marilyn Monroe Mondays.” Monroe — born 100 years ago on June 1 — stars in the comedy gem “Some Like It Hot” at 8 p.m. and “Misfits” at 10:15.
