If people read this review and haven't seen the episode, there may be possible spoilers.
I cannot believe they killed Alex. I actually cried when that happened. Charles Widmore is an untrusted a**hole. I really dont like him. The doctor from the ship being the washed up body didn't suprise me as much as I thought it would. I was expecting someone like that to come. Ben's flash-forward sure was messed up, but it was decent. When Sawyer found Claire after the explosion of the other building, I thought she was dead. I was about to cry there. Overall, I thought this episode was very well written, and I loved it.
