I loved it too, but there were little things that nagged at me.

Sayid wound up all ecstatic with Shannon instead of Nadia? Really?

And where was Mr. Eko?

And why didn't Sun and Jin and Claire, etc. wait around for their respective kids to join them too? No Ben/Rousseau/Alex reunion?

Rumor has it Mr. Eko wanted considerably more money than a reasonable day-player rate to come back from London and do the finale.

I think MGK says some cogent things about the Sayid situation.

The kids, I will grant you. There's not enough handwavium in the world for that to really make sense.

I thought it just meant the kids were still alive, in the regular timeline, living their lives and building their own groups of people who were the most important to them. The Losties didn't bring their parents, after all.

Also, Ben stayed behind in the sideways world, which gave him more time to be with Rousseau and Alex. That just seemed implied to me.
