TV Shows That Went Downhill After Season 1
5. 'Glee' (2009-'15)
Jukebox dramedy Glee was a hit as soon as it premiered in 2009. Its mix of pop hits and good-looking teens proved worthwhile for Fox. Season 1 is generally considered the best, however, as the show lost steam over the years. Season 3 saw a new cast of characters and things weren't the same after.
