Fox has renewed Glee for a fifth and sixth season, the network announced today. Fifth and sixth. That is so much Glee, America! Do we really need this much Glee? Maybe we should consider the idea that we've reached our necessary Glee levels and do not need any more Glee, and that additional Glee might actually start to harm us. No word yet on which cast members will or will not be returning, or any analysis of which songs are even left in the pop canon that the show has not yet covered.
