I thought this was a much better episode than last week's. Funny after all the arguing in last week's thread over whether the Doctor kills or not, the next episode brings the question out in the open by having him choose to at first kill then help a war criminal (albeit reformed). Apparently the answer is he will kill, but companions help him keep his moral center. There were no companions around last episode to stop him. It was nice to see Ben Browder again. He's definitely no stranger to SciFi, but I still never expected to see him on Doctor Who.
