Freaks and Geeks is the perfect example of a brilliant show cut down in its prime, cancelled after a measly one season. There's no question the show was overflowing with talent: Judd Apatow has become a force to be reckoned with in Hollywood, and Seth Rogan is also making his mark. If that weren't enough, Busy Phillips wrote the hilariously idiotic Blades of Glory screenplay. Add to the mix James Franco (Spiderman), Jason Segel ( Forgetting Sarah Marshall), and the veteran actor Joe Flaherty, and you begin to wonder why exactly this show got canned.
Okay, maybe the writers and cast were talented, but the show still sucked, right? Well, it won Emmys and countless other awards, gained a massive cult following, praised hither and yon by critics, and still sells quite well on DVD. So, what's the problem? Why was it cancelled? Sadly, I can't really answer that. According to http://www.brilliantbutcancelled.com/ it was a lack of love - no one cared enough to try to make it work.
Thinking of the untimely death of "Freaks and Geeks", it got my mind wondering about other shows cancelled before their expiration date. "Arrested Development" comes immediately to mind. "Star Trek" supposedly couldn't stack up against "Laugh-In" and was yanked. Everyone tells me the new "Battlestar Galactica" was a piece of sci-fi heaven, but got 86'd. I know there's a bunch more, but I'm way too busy (i.e. lazy) to try think of some more, so may need a little help.
