Lost is almost over

Damnit. I've invested 6 years of time into watching this show.. and I've been a loyal viewer since. Im pretty mad they had to pull it all together so quickly but whatever. And now i have three days till the final two and a half hour finale. I have no idea how it will end. But if they don't kill Flocke, Desmond was used to be conscious of the two timeline things. and if they fail, he will be used to bring them back to the island as a failsafe. Then the cycle goes in and the story starts with them going to the island again. Boom.
