Good set up episode which also manages to give precious details about Michael's journey.

At this point Michael's plan was quite predictable but the backstory was still very engaging. They plays a lot with the viewers emotions, dividing the audience, after all, Michael is just a father trying to do all it takes so save his child. I don't necessarily agree with what he did, but his motives are very good and well written and adapted to the plot. 
The scene with Walt was good, from that dialogue we easily understand that the Others are actually an high tech organization, I'm curious to know if they have something to do with the DHARMA Initiative.

I liked the main group plotline. Sayid is very smart and now that Jack knows the truth, I'm very curious to see how the journey will unfold. 
Sawyer and Jack dialogue was nice, I hope Sawyer will slowly reveal his human side and eventually seek redemption.
I liked Charlie scene with the heroin.
