Thoughts:
I enjoyed the finale. Nora's tale is a bit ambiguous, left open for the viewer to decide whether she really went through or not.
After I first watched it, I believed her. But then as I thought more about it, I think there's one specific reason why it might not be true. This episode is filled with foreshadowing, and earlier on, when Nora is yelling at the nun over her doves, the nun ends up telling her "I'm not trying to sell you anything. It's just a better story"
This is what I started to think about after watching the episode. Maybe she didn't really go through with it, maybe she didn't see her family or decide to come back. Maybe she backed out at the last moment, and feeling so ashamed, alone and afraid (and proud, because she's always been prideful and stubborn), she decided to stay in Australia, isolating herself from her friends and past. She talks to Laurie every now and then to feel connected, but mostly for therapeutic reasons. Maybe she just told an alternate version to Kevin because, "It's just a better story."
Or maybe she actually went through and everything she said, really happened. Which I wouldn't mind, except for the part about her finding the original inventor of the machine, and having him build another one. Out of everything she said, for some reason that seems the most far fetched.
There are still some unanswered questions, like
what was up with the dogs in the first season? How does a dog get stuck inside of a mail box? What was with Dean and his whole schtick? I know he apparently just went crazy towards the end, but he seemed more lucid in the first season.
The Guilty Remnant was just a crazy cult it appears. Which kind of takes the fun out of their plot line. Just a bunch of crazy mute people, wearing white and chain smoking for no actual reason, and no mention of them in the third season besides the drone strike.
I'm guessing Kevin really isn't immortal, assuming his heart attack was real. And that opens up even more questions, like how he kept going back and forth between realities or "life and afterlife", how he was able to be poisoned, shot, buried alive, and drowned, all to just come back like nothing happened. It's confusing.
Of course, Lindelof is known for his ambiguous storytelling and unanswered questions. Atleast there was more closure in The Leftovers than, say, Lost. I was hoping he wouldn't make that mistake again.
