Few shows in television history have the history of Glee.
It premiered in 2009 to giant ratings and critical acclaim, combining music, comedy and important social messages like no series ever before.
By the end of its run in 2015, however?
The program had practically become a parody of itself, limping to the finish line with a shortened season and zero critical acclaim.
Its cast, meanwhile, was mostly full of previously unknown actors and actress, some of whom followed up their time at William McKinley High School with success on the big or small screen ...
... and some of which met a tragic end.
