Putting all thoughts of 'seen this before' out of my head, I really liked this episode. It seems that this series is shaping up to be pretty darned good, considering the slating that the last series got.
Liked the fact that we learned more about Jacks' past, fleshing out the character, the tortured soul that he is.
I'm also assuming that when Adam disappeared back into nothingness, that all memories he altered would revert to their original state, meaning his last act of disrupting Jacks' last happy memory of his family was futile, given that he would have known that Jack was going to Retcon himself anyway.
I have to say that the city on the Boeshane Peninsula looked very futuristic-Bauhaus from a distance, but slightly Mediterranean up close, although still no idea where the Peninsula is, no planet named yet. Is it in or anywhere near The Silver Devastation (home to Boekind)?
