I was quite disappointed in the end of LOST. While I’m happy to leave some questions left unanswered (like “what is the island anyway?”), there were some things that were either unanswered or glazed over that detract from my enjoyment of the overall series and leave me wondering what message the series put forward. Reason vs. faith, fate vs. free will, loyalty, and the problems of secrecy were recurring themes throughout the series, and the themes seem somewhat unresolved.
The characters are of course rewarded with heaven in the end, but was this because of their faith, loyalty, etc. or was that irrelevant? Did the characters who died serving Jacob die for a just cause? Could all of this have been avoided if just a few people had been more forthcoming about what was going on on the island? I don’t know.
I do have a few speculative answers for some of the nagging questions remaining after the finale.
