if claire, kate, sawyer, other dude and pilot made if off the island, why were they in the sideways reality? plus the plane shot at the very end didn't appear "fixable".
"I was definitely entertained for six years. However, I am disappointed because I feel like I never got any real answers about what the island actually was, what was Dharma’s purpose, the numbers, why couldn’t pregnant woman give birth on the island, why did Widmore want it all so much, etc etc etc. We wasted whole seasons on who exactly Ben Linus was, the creepy Russian with one eye, all the psycho Dharma others, the "specialness" of Aaron and Walt, when none of it apparently mattered, and was only 1/25 of the plot. I feel like the writers just got lazy and went with the whole “mythical magical Jacob†vague storyline to explain away six years of intrigue. Loved all the reunions though (especially Shannon and Sayid and Sawyer and Juliet)." -random internet person
