"Lost" is coming to an end. I really liked the first season, but somewhere along the line it became frustrating that they just kept throwing in new weird stuff without any explanation about what was going on. It felt like they were just coming up with twists and strange developments to keep you interested. However, after a while that starts working against the series because if it can mean anything, it can also mean nothing.
Naturally, that's not how the producers see it. In a New York Times interview, Carlton Cuse, one of the show runners, says, "We think it would be sort of enormously both presumptuous and frustrating for the audience to have someone say, “No, what you think is wrong because this is what Damon and Carlton said.” We think one of the things that’s been the coolest about “Lost” is that there’s a lot of intentional ambiguity, and there’s a lot of room for debate and discussion."
Of course it's a challenge to try to fashion a story when you don't know how long you have. The show runners admit that in the second and third season there was a lot of improvisation because it wasn't clear whether they were in the beginning, middle, or end of the time they'd have to complete the story. Also, one of the actors playing a central role didn't like being so far from home and quit, and that required some scrambling to adjust the story.
It'll be interesting to see how they handle all this in the movie-length finale. There are so many strands to tie up that any explanation probably will still have to be vague and ambiguous. But one thing that's sad is that, as Cuse points out, it's the end of an era for shows with such big production values:
"Here we are, we’re shooting a show, there are somewhere between 425 people who work on the show, 325 in Hawaii and 100 here in Los Angeles, we shot the show on Panavision, 35-millimeter film, we had two full crews — the scale and the scope and the size of this, this is the most expensive television series made anywhere in the world. And in this media landscape, it’s incredibly hard to capitalize something the way “Lost” has been capitalized. We have a fractured media environment, and there are many more choices, but as a result there are smaller resources for every show that gets made..."
