After they filmed the pilot, the producers of "Lost" reluctantly gave the network a series treatment they could "relate to." The island's not supernatural! There's a rational explanation for everything! It's a medical show! (think "ER") It's a procedural show! (think "Law & Order") It's a lawyer show! (think "L.A. Law") It's a soapy but not cheesy character drama! (think "The O.C.") It is NOT sci-fi or serialized, and there is ABSOLUTELY NOT any central mystery that we need to solve!!!
"Does it make you feel any better than the creators of Lost never had any intention of telling you what the hell was up with that random polar bear? Probably not: "No — we're not gonna tell where that polar bear came from, but we're all about answering the rest." The rest? Really? A recently leaked document from the show's beginnings reveals an entire structured layout for the show's start, middle and end. According to Damon Lindelof, the document is actually what the network wanted, and what they struggled against. /Film explains, having spoken to Lost's creator about it all: "This document outlines the version of Lost the network wanted, but one that Lindelof and J.J. Abrams didn’t." Basically: "ABC picked up the show, which never would have happened without this document. However, once those writers got to writing the actual series, many of these ideas got thrown away."
