This episode was actually good, but compared to the episodes before it didn't blow my mind, so I gave this a 3 star rating. Despite, there were of course great moments in it.
Episode's title in Germany is "Das weisse Kaninchen", which is a word by word translation of the original title. I'm relieved, that they don't seem to change them for now, as I think they are always good choosen.
I like the beginning scene, when Jack hurries to rescue Boone out of the water. The music and the camera work does it make kinda hectic. I felt like being Jack on that scene and felt his inner war of what to do. It's understandable, that Boone later says Jack shouldn't have rescued him instead of the woman, though it's not really fair to blame him for his decision. I mean, Jack wasn't able to rescue both of them at the same time and Boone was looking like drowning either. Should he have just let him sink and swim to the woman, he even didn't speak any word with?
The man with the suit scenes always give me goosebumps. The way he just stands there and disappear. I still wonder who that person could be. I'm pretty sure, that it's not Jack's father, even when he imagined his face in him. I think Jack was just seing what was flying around in his head. But I may be wrong with that.
I always enjoy the Sawyer scenes! Like the one, when he talkes to Shannon, calling her "sticks" ("Stelze" in german btw, which means exactly the same. I just looked up the original nickname in the web and was totally amazed about the amount of nicknames he uses for everyone. xD I love that!). I think he already became my favourite character.

The way he just is sitting there in coolness, watching the others. And wouldn't you know, they are suspecting him to have stolen the water bottles? Sure.

But I knew he wasn't. Though I thought it was actually no one of the survivor group at all. Like I mentioned in another comment, I think that there are others at the island.
I hate Jack's parents. How can parents say such things to a child? The mother is almost even more unlikable as the father, when she wants Jack to bring back his father, using the words "to ME" not "to US". But Jack is quite a good leader, when you think about how he had to grow up.
I totally loved the scene, when Jack was following the man in the suit through the jungle - was actually my favourite scene in this episode. I love that the scene was showing like we would see everything like Jack does, the camera shaking and the view sometimes impaired, near to powerlessness.
At the scene, when Locke was stretching out a helping hand to Jack, I was awaiting to see his father pull him up. Ot at least that he would see his father's face as a Fata Morgana in Locke.
I liked the scenes with Claire and Charlie. I think they would make a sweet couple someday. I'm looking forward to both of their backstories.

Locke seems to be totally satisfied, since he has seen the "beauty" of the island. He always wears a smile on his face, even when the others are looking kinda shocked. I wonder, when he gonna tell the others about it or IF he will at all. I imagine such a beautiful creature with a colorful feathering and eyes like crystals or something like that. A dangerous but beautiful creature. I also wonder how Locke survived the encounter with it.
Ohh the porcelain dolls gave me nightmares lol. I hate dolls, as they really scare me out. xD Portraits with serious looking persons on it does the same. Oh and little girls with long black hair and a teddybear. Haha
I like to see someone else in the flashback scenes like this time Jin, when Jack was talking to the airline woman. And I was pretty sure to see the same scene in a Jin or Sun flashback at one point.

This makes the show totally interesting!
The episode's ending was pretty sudden I think. Kinda unusual when you look at the great ending scenes of the other episodes before.
