From a plot standpoint, I would agree.
From an acting and directing standpoint, I vehemently disagree. This episode contained some of the best acting and directing of the entire series. The scene with Sun and Jin's father was heartwrenching and nearly brought tears to my eyes. And that was with freaking subtitles.
Look, we can't have Locke-type episodes every week with stuff blowing up and secrets being revealed. Some weeks, we get to soak up the plot, have things move along, have questions answered. Other weeks, we are treated to incredible acting by the finest ensemble cast on TV today. When the show is over and we know everything there is to know about DHARMA and the monster and all of the island's secrets, it won't be the plot I will remember. It will be the outstanding performances by actors like Naveen Andrews, Jorge Garcia, Michael Emerson, Yunjin Kim, to name just a few. That's what will make it so, after knowing how everything works out, pull out my DVDs and watch LOST over and over and over again. (not to mention the directing, music, etc etc etc...LOST is just an awesome show!!)
