In the comments, hunter1968 called the episode boring and Regula Oblique agreed and even went as far as to say, "I'll take season 3's Expose with Nikki and Paulo getting paralyzed by spiders any day over this sloooooooooooooooowwwww episode." Yikes!
Okay, well I will admit that it was a slow episode compared to other Lost episodes, but I thought it had some great moments. I was moved by Sawyer's depth of feeling toward Juliet, intrigued by the infection and being "claimed", and I loved seeing the Rousseau version of Claire. I also like the parallels between the flash-sideways and the different timeline flash forwards.
Carlos had this to say, "It was a bad episode. However, I think it was one which sets things up, which, I believe, will be appreciated more in the future."
Yep, I agree with that. If you look back at past seasons, Lost has a tendency to start off with a bang and then slow down a bit with the second or third episode to set things up for the season.
