I most say, the min feeling after this episode is sadness - I loved the old planet - it has been their home for three seasons. We knew the mainland.. that planet had fantastic storms. And whales. It was their home. Now this is gone like so many other things. The city is badly damaged and I hope we will not get next episode will hole and beautiful city as it would look stupid. Elizabeth Weir as a commander is gone, so it could be said - it was end of an era. And it will be hard to let go.
But the episode itself - all the thing on replicator planet, all those brave things, Elizabeth challenging that leader... great episode.
