A hit sitcom built on often-raunchy material, starring Charlie Sheen and, later, Ashton Kutcher begins with the premise of a Malibu bachelor (Sheen) whose life is disrupted when his brother and 10-year-old nephew move in with him. In the ninth season, Kutcher replaces Sheen, playing a billionaire with a broken heart. Briskly written and performed, the sitcom had fun spoofing Charlie Sheen's bad-boy reputation (which ultimately led to his exit from the series) and Jon Cryer's nervous energy.
