Not really sure what to say about this episode.
In general, I've been taking a "sit back, relax and enjoy the ride" attitude. I'm glad I did, because while the episode was entertaining, it wasn't very good. They spent a lot of time on the teen Jacob and MIB, both of who fumbled through their scenes and really didn't give us much (especially emotional attachment).
I think it was meant to be more spiritual than it came off, but I was happy we learned about Adam and Eve, smokeys origins, and what the deal is with the island.
Smokey as a Jeanie in a bottle (so to speak) is about the most plausable explanation I've heard so far, but he doesn't grant wishes, just promises and death. It's funny that MIB took his fake mom's words and came to the same conclusion that she did while living in the village. “They come. They fight. They destroy. They corrupt. It always ends the same.” I guess we find that he is just like the fake mother. He used the villagers as a means to an end.
The question is was she smokey (occupying the sould of the cave)? We could also bring up the nature vs nurture argument, but that would really suck up more time than its worth.
Jacob somehow sees it differently and has faith in humanity.
The mother mentions there is only one protector. Is that protector MIB? Is he the one that kills, unknowingly protecting life in the process and is the true reason he can't leave? If he does, man will gain the "secret of life" and go on to fight, destroy and corrupt it, thus ending all life?
If so, I guess the next big question is why Jacob is still there (well he's dead now), but he said its because it's his home. Did he do it just to save humanity from itself by keeping MIB on the island? Did the fake mom save them the fate of living alone and having each other for eternity (or until someone kills them)? We know Jacob could leave the island, but chose to stay. Is MIB's judgement so short sighted that he can't see the true nature of the island, or is he the spirit of death itself.
There's so many unanswered questions they could have addressed here, why these folks are brought to the island being the big one. I'm a little dissapointed they didn't do more with the episode, since there are so few left.
