I still find it ambiguous. All I can go on is what was shown, not what the producer said outside the show itself. I saw Eleanor dissolve into little golden lights that floated down to earth and caused a stranger to do something nice but small to make Michael slightly happier for a second. Whoa! Nirvana! 😩 The scene gave no indication whether or not Eleanor's golden lights could keep going and spark other acts of kindness or if her consciousness was still present or what.
I think what throws me off is that yes, they are dead and their bodies are long gone by the final episode, but their consciousness still existed. What made them them still exists in the conceit of the show. Anything that ends that consciousness is basically "killing" them. This doesn't happen in real life IMO because once the brain is dead then the consciousness is also dead, but in this show your consciousness can "live on" even after your body is dead so IMO it is a second death for that consciousness to be snuffed out.
Is Eleanor conscious in the glowing lights? Are the glowing lights alive in some sense? Do they have free will? Do they continue to exist or do they go out after they perform their tiny, almost insignificant act of kindness that seems kind of small and weak after all that striving and learning. How is being a floating light more fulfilling than what you could be doing in TGP with some kind of incorporeal body and other people to talk to?
Well, I've also had these experiences and it did strike me as depicting depression/suicide. It doesn't necessarily make me think they were glorifying suicide, but the way Jason and Chidi acted after they felt the urge to go through the door very much seemed like depression to me.
The actual going through the door wasn't violent and wasn't being suggested as something you should do while you're still alive on earth, so it doesn't strike me as saying people should kill themselves if they feel like it while living. But it did seem to show a cessation of consciousness, which is close in my eyes.
I guess I'm just not in the head space to feel that oblivion is perfect bliss and that may lead me to be disturbed by this finale while others might feel comforted by it. I like the idea of Chidi's wave speech in relation to when we die on earth because I don't think there is an afterlife, but in the universe of this kind of show where there IS an afterlife, once you die you should not have to die again. That just doesn't make sense to me.
