Lost is the best tv series I have watched, hands down. There is so much about this show that interests me. It is definitely a must see. Things do get very interesting in the middle, and I know a lot of viewers lost faith and didn't keep up with the series. However, I enjoyed it until the very last episode. While it wasn't my ideal choice for them to end the show like they did, I'm not sure they had too many options...Best characters, best story, best script = best show.
My favorite character is definitely Sawyer. No contest.
