FYI, "Lost" is having its final season next year. It was announced during season 3 that there were going to be three 16-hour seasons (that turned into one 14- and two 17-hour seasons because of the writers' strike) and then the show would be done.

While the show lost its way during season 2 and the early part of season 3, once the writers knew exactly how much longer they had, it got much better. By the end of season 3 to now (post-season 5) it has consistently been as good as, if not far better than, season 1 ever was.

But rest assured, it won't be "renewed" after next season.
