You is an American psychological thriller series that premiered on Lifetime in September 2018, then became one of Netflix’s surprise hits, airing for five seasons, through April 2025. It was developed by Greg Berlanti and Sera Gamble, based on the novel by Caroline Kepnes, and it revolves around Joe Goldberg, an obsessive bookstore manager whose obsessions lead to murder and chaos. What started as a fairly unassuming Lifetime drama quickly became wildly popular after Netflix gained the international rights, achieving over 40 million streams in its first month on the platform.
