The opening of this episode is superbly done, playing with the change in the timeline by showing Forest Gump-style newsreel footage of Hitler arriving in New York. From there, it’s back down to mediocrity. The politics between the Nazis (who are desperate to get their hands on new weapons) and the alien Vosk (who is reluctant to hand them over) doesn’t come to more than posturing between the two commanders.

There are some clever ideas, particularly Vosk’s speech about how time travel can be used to perfect his race - very Third Reich. But the only real moment of tension comes when the crew realize how the changes in the timeline were brought about, centering on an event in history that occurred before Vosk arrived. However, the thought that even if they manage to kill Vosk things may not revert back to normal is quickly glossed over in the wrapping up.

VERDICT: 4/10
