Yeah, I'm a bit ticked off as well. J.J. Abrams was interviewed on a local radio morning show a little over a month ago and he said that the finale would answer all questions except maybe one or two (gotta have something to make people want to come back for season 2). But I feel like nothing was really answered. No reason as to why they were there, nothing about the numbers, nothing about the Black Rock other than it's a big ass ship that somehow got stranded two miles inland, nothing about what's in the hatch. Nothing was answered.
We were only left with more to ponder.
What will happen to Walt?
Are Jin and Sawyer still alive?
Will karma strike the pirates and they will be stranded on the island as well only to become yet another adversary for the survivors?
What the hell is the black cloud (some people are hypothesizing that it is a cloud of nanobots - it's the only thing that can look like a cloud, take the form of something else, and actually be able to exert the force necessary to drag a person through the woods)?
Yes, the episode was thrilling as hell just like any other. Actually even more so. But there are too many loose ends to resolve. Finales need to resolve something.
But I will definitely still be tuning in to season 2.
