Average. Some nice setup for next week, but still just setup. The Caprica City flashbacks were interesting, and beautifully shot, but they would have been far more appropriate somewhere in season 2 or 3. In the penultimate episode of the series, they just had me wishing for the first 15 minutes of the episode back, for something more relevant in the fleet's present day.
I am very much looking forward to next week, because whatever it is, I'm confident it'll be one hell of a frakking show. And despite the ups and downs of this season, I am going to miss this show more than any other departed favorite.
