It all began when, in an Instagram story, Millie expressed her support for Joe's character, declaring, "So I've just started watching that new show 'You'... He's not creepy, he's head over heels for her, and it's okay... By the way, I know everyone's gonna be like 'Ahhh, he's a stalker, why would you support that?!' But seriously, he's in love with her... just watch the show and don't judge me for my opinion."

However, her perspective sparked a whirlwind of reactions from fans and onlookers alike. Some social media users didn't quite see things her way. They pointed out the problematic message in romanticizing Joe's not-so-great actions. They had a valid point – glamorizing his stalking and violent tendencies could send the wrong message, especially to younger audiences who might think that kind of behavior is totally acceptable.

At that time, Twitter was abuzz with opposing views directed at Brown. One user urged, "Can everyone please ask @PennBadgley to have a chat with Millie Bobby Brown and enlighten her about how Joe is a creepy stalker, thanks." While another user argued: "Millie Bobby Brown saying it doesn't matter that Joe from 'You' is a serial killer because he's in love with Beck is some serious 14-year-old energy."
