Is that it

I watched LOST last night... at the end All i could think was "thats it".They are dead, what about the electromagnet fields, the dharma progect, the polar bears, the wheels, the time travel..... But the more I think about it, I'm not sure what i expected. I am trying to have less expectations. I just want to enjoy what is offered. I wanted answers. But are there answers, is there a truth or a right or wrong? I struggle with this and constantly remind myself. Yes this is it!
