1. Lizzie McGuire (2001–2004)
Experience the turbulence associated with middle school— heartbreak, mean girls, drama—alongside 13-year-old Lizzie (Hilary Duff) and her buds Miranda and Gordo. Nothing screams adolescence quite like this Disney throwback. Plus, who doesn't love when Lizzie's illustrated doppelgänger shells out her opinions? To kick the nostalgia factor into high gear, Disney revealed that Duff will reprise her role in the Lizzie McGuire reboot, which is to air on Disney+ this year. Rejoice, millennials!
