Cory Monteith Glee Tribute

So today  I saw the glee tribute episode to Finn the character played by Cory Monteith. From beginning until the end it was sad. The characters were angry, sad, angry, sobbing, acting like kleptos. But the one thing that grabbed my attention and made me feel the saddest was Lea Micheles tribute towards the end of the episode. Superb performance from her.
