A show with a great potential, first 3-4 seasons are great, building a great story and great characters. One would logically expect the next 2 to be great as well and an ending where everything comes together. Instead, it is an unfinished, experimental show, seasons 5-6 being the worst and show dragging on an on with purposeless flashbacks and flashforwards and sideways, nothing makes sense at the end, puerile ending makes the whole show worthless. The show explains through numerous flashbacks how characters' pasts are linked together and how they would be tied together if they escaped the island and if the plane would have never crashed, but they explain poorly how they are linked to the island, why are they important to the island, only explanation is that Jacob: godlike figure, chose them because they were flawed.The proof that the show is unfinished is demonstrated by the fact that they had to make a 12 min prologue in which they explain very few things, but barely anything at all.
I would have liked a Lost where the Dharma Initiative would still be present on the island, would be some top secret organization who would conduct experiments and where the survivors where all selected and chosen to be on the island by the Dharma Initiative for experimental purposes. Where they would explain further the experiments conducted on the island and their motivations/ purpose. This is not the case, instead the show is throwing around all sorts of goofy poorly explained concepts of : time travel, immortality, life after death, spirits, religion: God and Evil, Adam and Eve and probably if the show would have went on for another season who knows even Jesus :D and the whole biblical story too, simply ridiculous!
