LOST ending

Are there any Lost fans on myLot? I am a big fan. Even still after 5 seasons. I only had some trouble when they flashed through time. There is one more season to go. If you're a Lost fan or not, I ask for your theory about the ending. What questions do you have about the serie that are unsolved maybe someone on myLot can help you clear things out. Do you have a favourite character in the show, maybe someone who's a bit similar to you? What did you really liked and disliked? What would you do if you were stranded on this crazy island? What is the killing black smoke monster?
