News that a planned spin-off of Fox's 'Glee' is dead might have some of its more ardent fans disappointed that they won't be able to fill more minutes of their life with 'Glee' related programming, but they shouldn't be fretting. In fact, they should be celebrating. They should be thanking the gods of television programming that a possible spin-off hasn't tarnished the legacy of the show they would give their very lives to protect.

If history is any indication of success, the odds of a spinoff being anywhere near as good as the original are slim at best. Sure, hit shows like 'Cheers' and 'Beavis and Butt-Head' gave us memorable classics like 'Frasier' and 'Daria' that, in some cases, even surpassed their predecessors. But there have been far more failures than success. These are the spin-offs that barely made it through their thankfully few miserable seasons.
