This episode to me epitomized why Lost has been underwhelming in the 2nd season. You've got all these great developments happening with the island map on the door, and they barely take time to examine those mysteries. Instead, they focus on characters we don't even care about. I really don't care about Mr. Eko and his church, Anna Lucia and I especially don't care about Bernard & his wife's pathetic relationship.
I do care about Kate, Charlie, Claire, Jack, Hugo, Jin & Sun, Sawyer, and especially John Locke. I think "the others" are cool, and the fact that they have one in their prison is riveting. I want to learn more about the others, the island, where the boy was taken to, what the black security system is, and what the code actually does. The writers are just giving us nothing. I expect things to pick up, but why waste time on extraneous characters we don't care about when there is so much better material to explore?
