I enjoyed the first season, put up with the second, and gave up after the third. I gather that tonight is the night when the world learns conclusively that the creators never had any idea of what they were doing to begin with.

UPDATE: No, I didn’t watch. No, I don’t intend to discuss the show on Monday. But here are a few reader comments:

The finale tonight was brilliant. I’d still recommend picking up wherever you started and finish it off.
And yes, it does appear that they knew what they were doing.

Another:

I still love it. Great characters, great acting, great production and great stories.
I think one big part of the reason I’ve kept watching was summed up in a review I read of the Season 3 finale: “If you want answers, find another island.”
The producers knew exactly what they were doing. Telling a series of interesting stories – not one larger story. That’s the big secret: it’s just like every other show, but better made.

Finally:

Tonight’s explanation episode lost me entirely. Those folks are way too full of themselves.
