It was a great ride though, well worth the trip!

I think really that's what it came down to for me.
We had all this weird stuff happen that they somehow gave very ordinary and plausible explanations to everything (time travel aside, though one could say it's always possible it could happen and we just don't know how yet). They hid all these puzzles and Easter eggs for us to find and discuss, like the numbers - then dismissed them as unimportant. Then at the end, they tried to eek those numbers back in with them representing the characters, but that made less sense than simply calling it a cool coincidence.
It all seemed to be building up to this big showdown between the Losties and some super secret evil corporation that was trying to harness the unique properties of the island for some sort of evil plan. We had not one, but two major evil characters angling to get what they wanted with the Jack and the gang in the middle. It had this truly sinister backstory woven in, with experimentation on multiple levels (including behavorial studies on the people who thought they were doing a study, yet their reports went to a big pile outside the bunker) and even mass murder.
Even the Jacob character made sense in the scope of the time travel aspect as a character caught just outside of time, like some temporal ghost.
Then, all the bad guys got their nuts cut off and Jacob ended up being this actively passive character that I'm surprised wasn't shown being nailed to a cross - yet suddenly he was the man. The smoke monster went from something awesome (potentially a nanobot security system) to a character apparently designed to remind Jacob of Mom's wine-making hobby.
With all that, it seems like the ending cheated by going after the tissue box instead of the slide rule.
They may as well have had Jack rescue some orphans from a burning school, then get hugs all around.
