I expected an explanation for the smoke monster, also why didn't jack become a smoke monster?
THERE was an explanation for the smoke monster, not in the finale though.
I really expected more/different of the last episode. :/
Because it was already dead. I guess you can't have 2 smoke monsters.
Am I the only one who noticed the light was dimmer when they went in and when Jacob kicked black smoke guy into the cave? The power was probably stronger or something and made him a monster.
