Neal Justin's TV picks for Oct. 19-20: 'The Simpsons,' 'Patsy & Loretta,' 'Modern Love'

Loretta Lynn visiting her hero Patsy Cline in the hospital is considered a musical milestone. The biopic "Patsy & Loretta" takes that introduction one step further, delving deep into their offstage relationship. You won't learn nearly as much about their individual importance as you did from Ken Burns' "Country Music," but a fantasy sequence that has Megan Hilty's Cline and Jessie Mueller's Lynn duetting on a cha-cha version of "Blue Moon of Kentucky" is dreamy.

7 p.m. Saturday, Lifetime

Rom-coms may be an endangered species in theaters, but the genre is alive and kicking in "Modern Love," a new anthology series based on the long-running New York Times column. Watching glamorous stars like Andy Garcia, Tina Fey and Dev Patel flirt and fight to coffeehouse music can get a little precious, but even curmudgeons will be forced to smile when Anne Hathaway leads a musical number in a grocery-store parking lot.

"The Simpsons" latest "Treehouse of Horror" just happens to be the series' 666th episode. But this is one of the least ghoulish of the Halloween-themed outings with rather tame parodies of "Heaven Can Wait," "Stranger Things" and "The Shape of Water." The most devilish joke comes at the expense of Mickey Mouse, an obvious dig at the Walt Disney Co., which recently took over 20th Century Fox.

7 p.m. Sunday, KMSP, Ch. 9
