Generally speaking, I was very interested in both Series one and two.
Series one, was complete and very good.
Not so happy about Series Two.
First of all, there was a very interesting plot twist at the start.
The tension throughout was very good. I eagerly anticipated the next episode.
The last two episodes, particularly the last episode was a disappointment.
It kept up the tension, and my level of interest.
It introduced some more plot twists.
So, what was wrong?
Incredibly complex and difficult to understand.
I no longer felt that it was based in reality, "something that could have happen".
So, a disappointing finale to a great story!
