The story (4.0):
We find out a little about Sheppards history. We see his ex-wife. I like characters from Sheppards live. They don't know where he is and what he is doing. This is preaty realistic.
But this is just behind story. Real story is about Replicator who was build by human scientist and escaped. Story has some twists and realy good ending.
The Production (4.6):
This episode is bather than the last one. Much more people (but once again not so many from atlantis) are involved.
When Sheppard is talking with his wife in the park, people are walking by. This make episode much more live.
They shoot replicator several time and injuries are visible, but still I think they can do it better.
There is enough action. Shooting and fighting.
