I thought it was beautifully done, but I was expecting something else. I loved the final scene with Jack's eye closing.

I wish we had more answers and explanations to things like the numbers, the whispers, etc. All they said in the show about the numbers was "Jacob had a thing for numbers". They didn't address the Valenzetti equation at all in the show.

Jae: Here's my take

1. Dharma Initiative was a group of scientists and mathematicians studying the unique electromagnetic properties of the island.
2. All "others" were people that Jacob had at one time or another brought to the island.
3. Miles was on the island as a baby. They didn't explain it well, but I believe his powers are from being around the electromagnetism from such a young age.
4. The kid was Jacob as a kid. Jacob was dead. MIB could see dead people and was seeing Jacob. They weren't clear about why dead Jacob showed up in kid form here and there.
5. Hugo and Ben were left on the island and the next protectors. For all we know, they lived thousands of years until they found someone to replace them.
6. Wasn't explained well. I think Michael was who the island wanted and Walt just happened to be along for the ride.
7. I need to re-watch, but Christian said something to the fact that it wasn't everyone's time yet.
8. Not sure, need to re-watch, but Christian said time didn't exist in that place.
9. Well the light was explained as Life, death, and rebirth. A little light is in every man. I think all of the light was too much for MIB's body to contain and for whatever reason, it turned him into the smoke monster. Kind of a comic book type explanation.
10. I think Ben just wasn't ready to move on yet.
