Okay yeah I cried cried cried. That was powerful.
Cons:
I don't really have the heart to nitpick and critique this finale. It was as good an ending to a TV show as I've seen in a very long time.
I guess... I wish it was longer?
Pros:
Just conceptually, this version of the afterlife is so freakin' gorgeous and ideal and even though I'm an atheist and don't think there's an afterlife, I... hope this is what the afterlife is like?
It just... works, on every conceivable level. Think about it. You die, and then you get to go through simulations where you learn about yourself, where you learn to improve and be a kinder, better person. And then after that, you get to go to a fun place where you can live whatever kind of life you want with absolutely no worries - the conventional dream of Heaven. You can be peaceful, or you can learn new things, you can achieve goals, you can repair relationships with people from your life on Earth. You can do whatever you want, for as long as you want. But after that, you go into the great unknown, and are finally, fully, at rest. We even see a hint of what these souls do when they're at rest - they linger within humanity, inspiring people to do better, to be better, thus continuing the cycle.
