This was pure setup which I guess was fine, but off the heels of what was quite possibly the worst ep of the show, an all setup episode does nothing for me.
This season has prepared me for disappointment, aside from the Richard ep and the Desmond ep, and I think there was an ep centered around Locke early, I've hated this season. So the Sunday will end this season, which I'm happy for but it will also end the series which will be a bummer.
And then for the next 5 years every new drama will be "mysterious".
