For an even deeper emotional punch, put on Taylor Swift's 'Death by a Thousand Cuts' after you watch. LaKeith Stanfield plays her ex, Nate, who haunts Jenny at every turn as she tries to enjoy her last few days in New York with her best friends Blair ( Brittany Snow) and Erin ( DeWanda Wise). Not everyone feels enamored with love on Valentine's Day, and for those who are looking for something a little bittersweet to go with their SweeTarts Sweethearts and chocolate Kisses, there's Netflix's Someone Great. It stars Gina Rodriguez as Jenny, an aspiring music writer struggling to deal with the end of a nine-year relationship as she prepares to move across the country to start the next phase of her career.
