Love lost

I've been watching the TV series Lost ever since its inception 5 years ago.

When I finished the 5th season a couple weeks ago, I couldn't help wondering if watching Lost is similar to some marriages:
You start off. The first season of marriage is great, it's more than you could ever have dreamed possible. You wonder what's in store in years to come.
The 2nd season is wonderful as well, and that comfortable feeling you have isn't a bad thing (you tell yourself), it's just that you're kinda used to how things go now and everything's still pretty glorious despite the familiarity and not-newness.
The 3rd season starts to put some cracks in the mold, but these things happen, right?
By season four you're sure it's not just you. Things have gone down hill. In fact, they've been going downhill ever since the second season, but it took you a while to realize it (probably because you're such a nice guy). Sure, there was that one instance, that one moment that made you remember all the glory of years gone by, but it was only an instance, a living, fleeting memory of the past.
The fifth time is done, not out of love (on your part), but out of a commitment. A commitment to see it through to the bitter end. Let's face it: your golden days are over, and so are theirs, and there's no use trying to find something new now. You've gone this far, and you'll go a little further still. So what if it's gotten ridiculous and unappealing? Love isn't a 24-hour happiness convenience store. Love is a slow, grueling march where people stick things out while championing words like 'apathy, familiarity, and lethargy,' even if they don't know what they mean.
