Another Judd Apatow-created series that ended way too soon: Freaks and Geeks. The sitcom follows a group of nerds and burnouts growing up in 1980s Michigan, and even though it got the axe from NBC after a single season in 2000, it helped launch the careers of several cast members, including James Franco, Seth Rogen, Jason Segel, Busy Philipps, John Francis Daley, Martin Starr, and Linda Cardellini, among others.
