I look at "Across the Sea" in two different contexts.
Viewing it as just a standalone tale of two brothers on a mysterious island it is a pretty decent story.
But if you watch it as a critical piece of the LOST mythology it fails on many levels and the cracks in the mythology's planning become evident. It gave us answers but they weren't the most satisfying ones. I also had a very bad feeling about the feel good mumbo jumbo surrounding the Light/Source. Could it live up to the big Mystery of the Island? Also we get our first indication of how MIB became the smoke monster and again didn't like it. Weak. Adam and Eve--okay but not mindblowing. So I have to say the idea of making Jacob and Smokey humans and not the first creations or even God or the devil are a little disappointing. I didn't care for Allison Janney. I didn't care for the mumbo jumbo of how Jacob became Protector. Also the more I think about everything Smokey is doing to get off the island comes back to his "Mother" telling him there isn't anything out there and he wants to show her! That is a pretty thin bit of motivation to explain his actions.
Everything kept building and building over seasons 3-5, more and more pieces coming into play and at the end of last season I felt like season six would take them the final mile in their development but I've kept waiting and waiting and nothing. And now looking back I'm a little surprised things were just left where they were and have not been revisited. I wanted more about the injections Des took in season two, more about what the monster did to Rousseau's team and why, more about Dharma and those in Ann Arbor, why Paul's body was taken last season to the Others etc.
When Widmore ominously hinted at the coming War I expected that would drive this season and be the epic vehicle to frame the season but looking back it was rather lacking in scope--it fizzled. Even moreso with the way Smokey was built up by Ilana and the early parts of this season as Evil Incarnate. Even Smokey as the season progressed became less malevolent despite what the writers suggested with the whole episode last week.
I also expected Eloise and Widmore to have a more prominent role this season too.
So overall pretty disappointing.
Across The Sea:
If this episode had come earlier in the season, it might not have been a problem. Three episodes from the end, though is a major problem. We just had four major characters bite it. Things are looking really grim, and there's very little time left with our remaining characters. So what do we get? An entire episode without a single one of the main characters, that focuses completely on the mythology.
I might take exception to this. This series has had such an expansive cast of characters that it has always spread the screentime around. MIB and Jacob are important characters and deserved their showcase.
LOST and other shows like it always sprinkled clues and built up the mysteries of the year throughout the season always waiting just right before the final stretch of the season to pull it altogether and showing their hand before launching into the resolution for the year. This was no different. I do think though the season could have been tighter and I question whether the writers needed 18 episodes or maybe I should ask did they do the best they could with them.
In the end, Lost was never a show about its mythology or mysteries. It was a show about the characters.
Totally disagree. One can argue that LOST was about more than just Mythology but to say it wasn't about its mythology or mysteries is ridiculous. Look into most threads over the course of the series, hang around the water cooler the next day at work and people are talking about clues, last night's twist, the big revelations, speculations, theories, what the statue was, who is DHARMA etc etc. Fans didn't spend hours on the characters or analyzing them they were busy scouring scenes for easter eggs and hints to help them unravel the mysteries. Why did people get frustrated at the stalling for answers in S3 if the show was about the characters. If that were the case they wouldn't have gotten frustrated--afterall who cares about the mythology we have the characters to watch.
What did the bulk of Q&As with L/C center on--mysteries/mythologies. Also the last two seasons -4/5 were almost entirely plot based.
I know producers of these big mythology shows love to say at the last minute it was always only about the characters but that is flat out BS. Moore did it with BSG and L/C did it with LOST. Why if the plot/mythology wasn't part of the show did L/C encourage fans to look for something more that they never intended to resolve always with their cheshire grins egging us on?
Kind of like blowing up Vulcan. Even if it was the worst move ever (and I don't think it was), there's something to be said for being daring enough to do it in the first place.
I hate it when writers pull cheap stunts like that for pure spectacle--just because they can.
