I'm feeling rather "meh" about LOST. I can't say I'm disappointed, but I definitely didn't come away from it going, "Oh. My. God. That was awesome!" There were some parts I liked (I really did enjoy the final scene and its circular nature), but I also have to suppress my urge to call "Bullshit!" on a couple of things (WAAAALLLTT!). And as Jin and Sun were the only paring I cared about I could care less about seeing any of the others making out. And some...just don't work for me. And the alt-world being what it was, I am now even more upset with what they did with Jin, Sun, and Sayid's island stories. They just don't seem fitting at all. A lot of the last season didn't seem fitting for that matter, but I've long ago just decided to shrug and go where the show took me. (I am, however, still trying to figure out what the point of the Temple was...)
All this said, I feel like the creators did a good job of doing what they wanted to do. I think the problem is that while creators were concerned with presenting themes and philosophy by exploring the lives of the characters and the connections they forged in the midst of all these mysterious circumstances, a decent portion of the audience was more concerned with the literal plot and explaining the weird backdrop and incidents in which the characters found themselves. So many times have I seen comments expressing the sentiment: "Who cares about who Kate picks, I just want to know [insert unanswered question here]," and so many times have I thought the same thing. Unfortunately for us, who winds up with who turned out to be of the utmost importance to Darlton. Hence why I feel "meh."
Ah, well, it was fun ride, and it does feel rather surreal to know that it is over. So it goes... One less show to watch next year... she thought wistfully...
