We've been trolled for the last 5 years.
Can't believe so many people liked the ending.
The 'big twist' of the flash-sideways was so lame. So many things could have been done so much better.
Effectively it all boils down to:
- An island which has a cork at the centre.
- Removing the cork, releases hell/evil upon earth.
- The evil on the island wants to leave, but can't because the island has a protector.
- The evil and the protector can't kill each other, so must live together for all time on the island.
- The evil can take the form of 'smoke' or people who have died.
- The 'big' loophole that one of them eventually works out (after thousands of years?), is that they can kill each other, but only if someone else stabs them before they have a chance to talk to that person (stunning script writing there!).
- As long as there is a 'candidate' on the island to replace the protector, then the evil still can't escape.
- The only other option for escape is to destroy the island.
- The island can only be destroyed by removing the cork at the centre, but this can't be removed by anyone (except someone who can withstand huge electromagnetic forces).
- Leaving us with:
The protector only needs to make sure he speaks to everyone on the island. He can keep a backup of 'candidates' on the island, in case he fails at this relatively simple task. And then make sure that you're hanging around the 'light' at the centre of the island, just in case a guy who's immune to electromagnetism shows up and removes the cork. Then make sure you just put it back in afterwards.
But remember that this equates to one of the best tv shows ever, because it started out with some fantastic character building and relationship development, and ended with an 'emotional twist' where we find out that they all 'created' a place where they could mill about, waiting for each other to die, and then all meet up and 'remember' their lives on the island.
Total letdown.
