If anyone wants to discuss the LOST finale, I'm here for it.
Let's start with the obvious:
They were not dead since the plane crash.
Basically every mystery was explained.
JJ Abrams only had input for the Pilot and very little afterwards. So no magic box bullshit.
Of course the writer were "making it up as they go", they didn't have a 6-years plan. But the themes and motives were there since the beginning. (in fact you can read the early outlines here: https://www.reddit.com/r/815/comments/13kr6ua/the_black_box/).
LOST was all about the characters _and_ it had a compelling mystery. It was perfect. Also it's one of the few media to get Time Travel 100% right (as in: internal logic).
One of the topics constantly running in my mind is Alan Moore saying that writing a comic, novel, movie, is an act of magic.
You write, or say, something. Other people hear, and their brain is forever changed. They will think and/or act differently.
So he truly is a wizard.
