Lost To End After 6 Seasons
Kristin from E! Online says:
ABC is set to announce that Lost will end production after two more seasons.That's excellent news. If they have a firm endpoint to move towards, we'll have less filler to put up with.
Updated: It's official now, but it's technically 6 seasons, not 5, so I'm modifying the thread title.
Thing is, the order is still for 48 episodes, they will just be broken down into three rather than two seasons. (The show's seasons to date have been 24 episodes each; hereafter, they will be 16 each.)
The Lost series finale will be episode 119. It will air in May of 2010. ABC's press release reliably informs us that the series finale will be "shocking."
