Yes, to the original (titular) question. I have seasons 1-4 on DVD and had been planning on getting them all and re-watching at some point. But no longer.
I never believed I was going to get a satisfactory explanation for the island or the mysteries surrounding it after season 3, when the 4th season went far enough into wacky territory that it could never be anything other than a “magic island.”
What I wanted was a satisfying resolution for the characters. I didn’t get it. Let me put it in terms of who I saw as the 4 main characters over the course of most of the show:
I guess the whole point of Jack’s character was to have him accept his fate as savior of the island. But since the island’s relationship with the rest of the world is never fully revealed or verified, all we’re left with is, “OK, I guess he saved the world… I think.” Did Jack’s ultimate sacrifice really matter?
John Locke’s story came to a pathetically sad and quiet end at some point in season 5, but even though he was a favorite character among fans, we didn’t know for sure until the 6th season that the writers had him killed off as a confused failure of a man, but tricked us by re-casting the actor as a brand new villain created just for the last season, like General Grievous.
I thought Kate was supposed to end up with either Jack or Sawyer, but she ends up with no one and does nothing in the last season, and ultimately serves no purpose in the series. She escapes with Sawyer at the end, but whether or not they get together after that is pointless, because they don’t show it, and more importantly Sawyer’s true love is apparently Juliet anyway.
And finally, Sawyer. What should have been the joyous reunion of Sawyer and Juliet in the alternate time-line, when they remember their life on the island together-- it turns out that was just part of remembering that they were dead, and that it was time to “move on.” That was the most emotionally effective scene in the finale for me until the ending undercut it and robbed it of its power-- what I had previously seen as Sawyer and Juliet rediscovering each other, with the joy of realizing they could now spend their (real, or so I thought) lives together, was really just them remembering it was time to go to church. Forever.
