EDM festivals are very, very cool
If you haven't guessed, the music festival in the film is called XOXO, and it is a big deal. Like, really big. I know this because the movie told me this many times. "I fucking love you, XOXO," Ethan shouts late in the movie, in case it wasn't already clear that you, too, should love XOXO. Also, XOXO must be cool because all the characters in the movie want to go there, listen to music, and have a transcendent experience. It was founded by a mysterious, reclusive DJ, and it takes place somewhere in California, so, like I said, very cool.
As the movie begins, we meet our fist-pumping young heroes. There's a romantic dreamer in purple lipstick named Krystal (Modern Family's Sarah Hyland), an aspiring music manager stuck working at his father's restaurant (Brett DeBuono), a couple on the verge of a long-distance-mandated breakup (Colin Woodell and Hayley Kiyoko), and a party bus full of tank-top-rocking bros who resemble an army of knockoff Channing Tatums. If all these people want to attend XOXO, you must also want to attend XOXO. XOXO gives you life.
