I feel they did a real good job with the death of Finn/Cory. Yes Cory died of an overdose and in the show Finn died. Kurt said it best why do we always want to focus on the how someone died, their dead, the how isn't gonna help you grieve any better. I think this episode was about death, and how it affects everyone from parents to family to friends. Think about how we treat people cause they might not be around the next day.
