I might have enjoyed this show more but the central concept is presented in such an unbelievable way that it makes it hard to enjoy. Obviously the concept of someone being able to transform into another person is nothing new but typically it's the result of something supernatural whereas this show presents it as more of a medical condition. The transformations themselves take a few seconds and are perfect. To present this ability in a more "believable" light it would have to take days or even weeks to transform and have various side effects and criteria. The idea that it's a natural condition passed down genetically but it operates as if a magical translation, just doesn't gel.

Adding to this is the inconsistent manner in which the metamorphosis happens both to the character changing and the target whose likeness they are taking. Sometimes it just seems like the writer had a plot point he wanted to fit in so they just decided that the "shifter's" ability could work differently in that scenario and no sense needs to be made of it because it's an absurd idea anyway.

Beyond this the show has some decent performances and general themes that seem interesting to start with but often aren't seen through in a satisfying way. Characters often react in unusual ways and either don't ask the most obvious questions or they exert their own restrictions even when all the evidence in front of them says it doesn't work that way.

Not his finest work but always nice to see my countryman Guy Pierce in something. His presence in this show has the added advantage of being able to force the Norwegians to speak English for the dumb Aussie quack.

If the core of the series had something more interesting to say and the Shifting ability was just a means to do that, I could accept it much more but it seems that the Shifting is meant to be the focus of viewer interest.

I'm yet to watch the last episode but hopefully it lives up to the the other reviewer comments about it.
