Who saw it? What the hell do you think happened? I personally really liked it , I kinda knew they were gonna go with a purgatory / afterlife theme since season 1... Let's talk about everyone's theories about what happened in the final episode! I think they didn't all die in the plane crash , but died when they did on the island ... for instance Mr. Eko was a drug dealer responsible for his brother's death (IIRC) and then when he redeemed himself was killed by Smokey and "passed on". Some of them made it off on the plane , and when they died later in life they all met up in their personal "heaven". Ben stayed outside because he was not yet ready to admit he was dead and pass on... he was not yet at peace.
