oh my god...
It really touched me..
It also helps I'm an extremely sympathetic person. It all just clicked for me. The ending vindicated it all for me. Sure a ton of mysteries we're left un-answered, sure a ton of new questions arose, - and sure, I would want to find out more - but what it did do was to bring to to an utterly emotional closure of a full circle. If you emotionally invested in this story, like I did, I don't see how you would think it was bad. It was a drama show along with a thriller/mystery. Mystery and thrill is not what we need in the final, those are the themes that set up for a cliffhanger, this was purely about the characters and their lives. What they answered explain the most important segments; the questions left are only minor one's in the grand scheme of things in my opinion.
Not many movies, shows or stories have made me cry, but the lost ending, it's just so tragic and happy.
