The Last Episode of LOST?

i have been an avid viewer of lost since it started and loved the mystery of the show. while i found the ending very emotionally charged and moving it still didn't answer any of our questions. we viewers invested so much of our time in a show that we came to love only to find out they had all died at some point in their lives and needed to find one another to move on. i have put so much of my time into this show wondering what the island is why women cant have babies and so on and nothing about the island, which the whole premise of the show was about was revealed, either the writers have done this to really piss us off or couldn't find a reasonable explanation for the answers to our questions.
