What the f**k was that all about? Just watched the finale and im as confused as when i started. Granted, i stopped watching after the 4th series but the curiosity value made me watch it. I knew that there would be somethings that i wouldnt get but that the big questions would be answered.
I know that since i didnt invest time in the last 2 series that ive no right to ask this but i would really appreciate if anyone could spare a few minutes answering these,
1. What was the story with the polar bears?
2. what was the significance of hurleys lottery numbers?
3. What the f**k did that ending mean? was the island real or was it the alt real?

Is it a case of just a poor ending, or is it far too complex for me?
Please please help my tiny mind from exploding
