Watch On

Genre: Crime thriller movie

What it's about: "Tuner" stars Leo Woodall as Niki, a piano tuner's apprentice working for Harry Horowitz (Dustin Hoffman). At a wealthy client's house, he accidentally crosses paths with a group of thieves led by Uri (Lior Raz). He helps them open a safe with the same skills he uses to tune pianos, and Uri offers him more work. Discovering that he could use money to benefit everything and everyone in his life, he accepts.

Why you should watch it: Our streaming editor, Rory Mellon, declared "Tuner" one of the year's most overlooked crime thrillers and a must-watch. Woodall is excellent, and his safecracking scenes are "electric." If you didn't catch this one in theaters, make sure to watch it now.

Why you should watch it: Before the season started, most people would have assumed this game would be a cakewalk for the Rams. But it's the Giants who are 1-0, and the 0-1 Rams suddenly find themselves needing to win against a tough opponent to stay in the playoff hunt.

Genre: Musical fantasy movie

What it's about: "Wicked," adapted from the musical and the book of the same name, is set in the Land of Oz before the events of "The Wonderful Wizard of Oz." It centers around the relationship between Elphaba (Cynthia Erivo), who would go on to be the Wicked Witch of the West, and Galinda, who started as Elphaba's classmate at Shiz University before becoming better known as Glinda the Good (Ariana Grande).

Why you should watch it: While "Wicked: For Good" got a mixed response, this first part of the duology received near-universal acclaim and a Best Picture nomination. Come for "Popular," stay for the showstopping "Defying Gravity."
