Given how pumped up I was for this episode, I came away somewhat disappointed. Finding out that the two were twins was interesting, but I thought that too much time was spent on when they were kids. I felt that the portion of the episode where Jacob and MIB were adults was disjointed and rushed. And I completely agree with azjepp that the whole donkey wheel scenario makes no sense at all. MIB’s comments about there being a lot of smart people who have figured things out was completely meaningless and smacked of a rushed answer to our questions regarding the islands electromagnetic powers, the well and the light. 30 years of MIB's life, where he gained all this experience and understanding of the island, were touched upon in one statement. I really don’t see how what MIB explained to his mother in the hole makes any sense in conjunction with the rest of the story. In fact, it actually raises even more questions for me.
The issues that the writers tried to address last night really needed at least two episodes to explore and properly resolve. Think about it...after nearly six seasons of build up, we had the entire mystical explanation of the island and its two principle players jammed down our throats in about 45 minutes.
Perhaps crazy womans statement to Claudia is the also the writers advice to us as well..."Every question [i answer] will simply lead to another question."
