One thing a lot of people don't realize about Lost (and what makes so many of your alls comments about "oh the writers are running out of material blah blah) is that the writers have known all of the things that happen in all 6 seasons...from season 1. They sat down, and wrote out this ENTIRE thing.
They aren't running out of ideas, the shows not changing, etc, ALL of this was written before the first season was done, and there is much proof on this, as it's stated many times in the special features of the dvds from the writers themselves.
Well that isn't true, for numerous reasons:
- Michael Emerson (ie, Ben) was originally signed on for I think four episodes but after the positive reaction to his Henry Gale character they kept him on. That means potentially no Ben from season 3 onwards.
- The writers wanted to explain Libby's backstory but the actress didn't want to come back, so they scrapped it.
- The writers have supposedly (only hinted really) that Juliet and Sawyer's relationship lasted much longer than it was supposed to following positive reaction to the LaFleur episode.
- Eko was written out of the show after the actor's parents died and he didn't want to live in Hawaii anymore.
- The Jack episode midway through season 3 (the one where he gets his tattoos, and also one of the worst episodes) has been described numerous times as 'stalling for time' because the writers were still negotiating with the studio about an end point for the series.
- Richard was supposed to be main cast in season four but the actor couldn't do it because of other commitments.
And so on. They have however said they know the start and the end point, but I think Carlton Cuse said that 'the path can change on the way'. So they're just as guilty as fiddling with things as other writers are.
