LOST was hailed as the best written and filmed show in its television era. Fans expected a the intertwined mysteries to unwind in a tight script of revelations and satisfying conclusions. To say there were stumbles along the way would be an understatement.
The biggest problem was with the biggest lie.
Recall, Daniel is sitting in his chair watching television when the news breaks that searchers had found the remains of Flight 815 at the bottom of the ocean. There were no survivors. Robotic cameras showed footage of the wreckage.
Recall, Naomi parachuted onto the island from the Widmore freighter. She told the 815ers she met that Flight 815 had been found - - - that there were no survivors - - - they were all dead.
Later, we were told that Widmore "faked" the Flight 815 crash site in order to "hide" the island. Except there are several problems with that lie within a lie. First, every aircraft has detailed serial numbers on its parts. One cannot buy one and change the parts IDs. It was totally implausible for a fake wreckage to be made with an actual plane because each plane is also registered in the U.S. Second, if the plane and bodies were found, the authorities would have recovered them for the sake of closure for the families. The impossible explanation was that Widmore dug up 248 graves to deposit bodies on his fake wreckage. Third, the freighter captained showed us the alleged black boxes from Flight 815. However, if they were recovered, they would never have been released to a private individual. The FAA and government would have kept them as evidence. So none of the "fake" plane wreck is real.
But the real kicker is that after the world wide Flight 815 found story was the Oceanic
Six showing up in Hawaii. If the plane wreck footage found all passengers and crew on board died, then how did six survivors wind up in Hawaii? The passenger manifest cannot be altered to add five more people after the fact. Further, when Kate was arrested in Sydney, the authorities would have noticed whether or not she was pregnant (as she alleged in the press conference). None of the O6 story arc made sense.
The reasoning behind Widmore's elaborate plans, including the extermination of everyone on the island, was also flawed beyond belief. There was no reason for the O6 people coming back to the island. If Widmore wanted to keep it a secret, that was already done when the island "moved" prior to the O6 rescue. The O6 people did not know where the island was; and more importantly, the world had stopped looking for the wreckage because it had been "found."
And there was no reason for Jack to concoct the Lie that the O6 were the only survivors of the plane crash. The miracle that the five survived the crash and washed ashore on an unchartered island was enough to "verify" the Widmore lie where the wreckage site was located and found. The exact opposite should have been said - - - to save their friends left behind the O6 should have mounted a public rescue effort to beat Widmore back to the island.
And the reason why the O6 or Widmore had to come back to the island was unclear. The O6 wanted to come back for the vague notion of saving their friends - - - but they did not know whether they were alive or not. Widmore wanted to protect the island by killing everyone on it. But if everyone was to be eliminated or exterminated on the island, there would be no protectors left.
In fact, only one person had the means to actually find the lost island: Eloise. If one really wanted to protect the island from outsiders, all you had to do was take out Eloise.
So, none of the elaborate lies makes any sense, individually or as a scripted collaboration of plot points.
