S2 was great, S3 just seems to be a repitition of S1 and 2. How much longer will S3 viewers continue to watch. Like Gypsy said, quit whilst it's doing well and will be a fond memory. Drag it out and it becomes dull, a joke and poor viewing figures. They knew when to stop Friends and Sienfeld. I think Lost will lose pace and viewers and then be pulled. Then expect some over hyped movie. Just like the X-Files.
