Now this really isn't true. A recap:
(SPOILER)Plane crashes, bunch of people die, some of them survive. Locke wiggles his big toe ala The Bride in Kill Bill and goes from being paralyzed to Hunter extraordinaire. There are polar bears and a Lostzilla romping through the jungle, as well as a crazy french lady who killed all her companions 16 years ago and has become...well ya know, crazy.
The little kid has weird "powers" and can make things happen by thinking about it. Turns out that Sun can speak English and she and Jin have a semi-divorce. Some poor extra named Joanna drowned, Charlie turns out to be a drug-addict, and Sayid gets tortured by the French Lady. Turns out they aren't alone on the island and Claire and Charlie get kidnapped by Ethan (Tom Cruise's evil cousin). Charlie is lynched, Ethan killed Scott, Claire is taken hostage, disappears for awhile and then reappeared with amnesia. Sawyer is taunted by a boar, Hurley built a golf course, and Kate sighs and looks off to the distance in a skimpy outfit. Shannon and Sayid get freaky, but before that Shannon and Boone have a semi-incestuous relationship and then Boone turns to Locke cause no one else can stand him, his eyes are too pretty. Charlie shoots Ethan 2 dozen times or so, Locke finds an alien hatch and then Boone dies just as Claire's demon child is born. In the meantime, nobody appears to be looking for them, and the raft got torched.
And that's all in the span of one month, I'd definitely say that the show was going somewhere. It works a lot like 24, every episode is only a day or two on the island. It isn't poor writing that's keeping them from wrapping up, it's excellent writing that keeps the show going. :)
