Glee
Following Cory Monteith's death on July 13 from a lethal mixture of heroin and alcohol, producers confirmed that his beloved character, Finn, will die in the third episode of the season. Although the show had recently reduced the roles original stars Amber Riley, Heather Morris, Mark Salling and Harry Shum Jr. in favor of promoting new kids such as Melissa Benoist and Jacob Artist, Finn was one of the show's most important characters, and the show will never be the same without him. Not only will fans never get real closure to where Finn's journey could have ended, but Gleeks must face the heartbreaking truth that Finchel will never end up together.
