While I thought the episode was aiming for a profundity it didn't earn or deserve, it seemed to have an actual science fiction concept to sell. And a downright creepy one at that: watching people relive their deaths, particularly deaths by exposure and dehydration. It beats Rush and Simeon going all Die Hard and The Lion King on each other.
I'm also not sure what the point of the others leaving and getting killed was. So we got a faith vs. science debate. It was almost like Remi Aubuchon was trying to point out how stupid the idea was for people to leave the ship in the first place.
And I'm still not sure what the heck is going on with Johansen's baby. So she fantasized the whole thing? Or the planet aliens gave her a projected fantasy? Or some other aliens? Or what?
But I'll overlook all that for writer Aubuchon actually making me care about these people. Everybody including the recurrings except James had their "moment," and there was the impression that these people actually had come together and were working for a crew. Young and Camille were back to a much more civil working relationship leavened with bits of humor. Rush was just enough of a jerk. Volker, Brody, and Eli should start a comedy team. Eli is back to doing kino recordings. And Johansen while not great, came across as the soul of compassion. Scott was the weak link, but he usually is.
What stood out was Greer, who for the first time seemed like a human being. He was still a gungho jerk sometimes, but whether he was talking with Park, or actually daring to insult Scott, or asking Chloe to forgive him in advance for killing her, it was a great performance by an actor more often that not asked to play soldier-psycho.
Chloe was a close second, and for the first time I actually cared that she was about ready to transform into something alien. It helped that she didn't mope, something else that the actress and Scott's often do. She knows what's coming, she deals with it. And... scene.
Overall, get Remi Aubuchon back to write more episodes. He came on as Executive Consultant this season, and judging from his writing in this episode, I think we can now figure why the show has improved in its sophomore season.
