4. 'Freaks and Geeks'
You want influential? Nearly every single person of this short-lived, much-beloved series has gone on to greater projects since filming the series 18-episode run. Creator Judd Apatow, James Franco, Jason Segel, Seth Rogen, Linda Cardellini, Martin Starr, writer/director Paul "Bridesmaids" Feig…the list goes on and on. What made the show so endearing comes across from the very moment it kicks with Joan Jett's "Bad Reputation" playing over the credits – it was real. Brilliantly (and painfully), Freaks and Geeks truly captured what high school felt like for losers, outcasts, nerds and dweebs everywhere. It was hilarious and heartfelt in the best ways possible and, like many of the world's ahead-of-its-time inventions, it was gone much too soon.—SCOTT NEUMYER
