I most say that episode felt little stronger than pilot. Maybe I am wrong and maybe just knowing the chars and the setting did it's part but that episode had much more logic, that kind of steady going, excitement and mixed with those flashbacks - it had quite an unique feeling and motion and I most say I liked it.
I also liked the whole space thing.. I mean.. they getting into the routines and doing their everyday stuff.. and even if I was not sure what they will come up, it wasn't bad storyline.. maybe too plain and too predictable after all those visions but good one, better than expected. Maybe when you do not expect much, the result is better and you are positively surprised.
Anyway, the good development were also on the "secret" side. I am still not getting what they are talking about but.. exciting.
