This episode is at the same time awesome and awful.
The plot is good, although there are some boring parts, and it is odd that Elizabeth and Rodney are so passive; they could have thought of more to do, like trying to trick Kolys. The last ten minutes are fast-paced and have some surprising twists.
Then there are the recurring characters of Todd and Kolya who are doing great jobs in this series.
This episode marks a turning point in the general story line. Up to now the Wraith are horrible monsters and very different from Men. Here the writers decided to change this. From now on they are driven by very much the same instincts as Men. They are no longer different. That takes away a lot of their menace; in fact, the Wraith seemed pretty harmless to me in all the following episodes.
Giving them some 'Common Ground' was an excellent idea, but the writers gave them way too much of it.
