That Lost finale sure was divisive! Some people loved it, others hated it and then there's a big chunk of people who want the internet to shut the hell up about it. Can't help you there, angry non-Losties!
Personally, I'm pretty ambivalent about it. By the time we were nearing the end of this last season it was obvious they were leaving all sorts of questions unanswered, and I accepted that. And I found myself emotionally involved in the finale itself as I was watching it. But still, I wish the finale had wrapped up the whole series rather than just the season 6 sideways timeline. I think I'm more annoyed that they wasted half the last season on that temple that ended up amounting to nothing than I am about the finale itself.
How about you?
