Novelist - I actually noticed that too, right off.
I am not sure what people are saying about the momentum talk. Every show went through this, and the good ones are getting through it. Lost has always had a dedicated audience, who are committed to the show. They come back when the show goes off for seven months, so I don't think seven weeks was a big deal.
The final two minutes or so of this episode is what I've always loved about lost. The soft, sad music playing while we shift to all the characters, really taking stock of where they are in their lives. Yeah, this show is about time travel. Yeah, this show is about bad people wanting to control everything. But it's also about a group of strangers, stranded on an island and trying to survive. My girlfriend just started watching this season, and I told her season one is going to blow her mind because there's none of what Ben brought us. It was about trying to survive, and a hatch on the island was the season-long mystery. And, to think, back then we were all astounded by it.
