It all came down to this - the entire show was building up to this very moment. The real chance to make everything right. To prevent the crash, to erase all the things that happened, all the miserable things, and to bring back all the people that were lost.
And to finally reveal the two sides - who's good, who's bad, who's Jacob, who's Christian...
The finale did a brilliant job keeping the story and character in balance. We finally saw all the flashbacks we wanted, and more. The whole episode had a season 1 vibe to it, which is welcome. But each flashback had something.. or someone in common. Jacob.
Yes, he's revealed, and his nemesis is too. There is a man, who wants to kill Jacob, but he can't do it himself, so he tries to find a loophole. And he finally found his: Locke. To understand all this, you need to watch the episode. It's just brilliant. The cold open is one of the best scenes of the show, if not the best.
Probably not. The best scene is most likely the ending with Ben and notLocke killing Jacob, thus having notLocke as the ultimate leader of the island. The evil has won? Well, not yet.
And of course, Juliet's last scene - the very last scene of the episode, where she blows up the nuke. There's acting, good acting, fantastic acting, and then there's this. If you didn't tear up at Elizebath Mitchell's beyond amazing performance, then you have no soul . The desperation, the struggle, the hopelessness was never portrayed so perfectly.
And the scene was capped off with the most brilliant ending of an episode ever: inverting the Lost logo - black text on white background. Ah, awesome.
Overall, this is the best episode of the show, and television, quite possibly. An amazing thrillride that gave us the last remaining pieces to unlock the mythology of Lost. See you in 8 months.
