The last couple minutes are a little confusing like the writers suddenly remembered they had a whole story about alternate universes they needed to connect to the overall story so they did it in the strangest way possible. That being said it is not nearly enough to ruin the show even a little. If you like alternate history shows I would HIGHLY recommend this one. It is four seasons long and has a respectable ending in all but that one way stated above. The main characters all have their moments and they all play their parts especially well. I really enjoyed from start to tragic end the Smith Family who from the beginning navigated their way through the Reich with ease until like Helen said to her increasingly questioning daughter the Reich came for them. Which of course sent them all off in wildly different directions and the final season is watching those directions unfold. The others stories were of different degrees of interest. I really liked watching Juliana Crane come into her own as a freedom fighter and although the Japanese storylines were often the least interesting to me the final season had the storyline go off in interesting directions. How long do you occupy a country that does not want you there?
This is a top notch science fiction alternate history story that I would highly recommened.
