I was sceptical about this series when I first saw it - in fact didn't complete the first series. However with series 2 the story progresses and the complexity of the situations the main group encounter is frustratingly gripping. I say frustrating as there is a part of this series I don't want to like - many parts seem just to be too much of a coincidence. How the main characters lives interweave and searches for loved ones come to fruition where of course in such a changed world these things without TV, radio or internet would be all but impossible. Also although the struggle for food and drink is sometimes shown mainly the characters seem to just produce a bottle of water from a backpack when required or the cars they drive have unlimited petrol. The message of this story is of course one of hope. The constant endeavor of mankind to keep going or die trying. Another disturbing thing is that I am almost envious of the survivors new lifestyle. Comrads to the death, a shared fate and an empty Britain where humans are just on the side of nature fighting for survival. Scenes of solitude set in either a grey cityscape or one of beautiful countryside. The silent and invisible virus is hiding and waiting..it will mutate and the last percentage of the human race face another test. Gripping indeed.
