I liked this mini-series. I wandered in looking for more of Benedict Cumberbatch's work after seeing his great performance in "Sherlock" (which I give 5 stars). This multi-episode story held my attention throughout, and Cumberbatch played well a genius astounded at what was unfolding around him. You can't look away from the screen though because they don't dumb it down for you. One must pay attention. Sure, there are definitely some holes in the fabric the filmmakers weave, and some thin spots you could easily rip wide open... but I am going thumbs up on the drama as a whole. I cared about the characters and what their ultimate fate would be.
Of far more importance however then the drama itself is the obtuse message delivered by the producers. We are on the verge of losing what remains of our personal liberty. The England painted by the film makers is not some maybe, kind of, far off 'Mad Max' could-be dystopian future. It is more of a 'Max Headroom' world that is looming up all around us. The world of The Last Enemy is just around the corner. In fact, we are at least half way around that corner. Much of the suggested technology appears to be here already (and micro-biologists ARE dying at an unusually high rate).
Many well-intended people --such as portrayed in 'The Last Enemy"-- think strong controls on the populace is a logical means of preventing terrorism and related crimes. History does not bear that philosophy out however. You can't gain freedom by removing freedom. Given the current state of the evolution of human consciousness, powers given to the Government are used. At first. Then they are mis-used. Then they are ab-used. Every single time. Treatments such as 'The Last Enemy' help point out the futility of 1984 style controls placed on the populace. Our best way out of the dilemma the world faces is instead through individuals raising their own consciousness. We MUST evolve or freedom WILL die.
btw - A title I can think of that might interest those who liked this film is the British political mini-series 'The Amazing Mrs Pritchard'. For those wanting to learn more regarding the themes presented in 'The Last Enemy' have an abundance of choices in video. Two that come to mind are the black dystopian comedy from Terry Gilliam 'Brazil', and the documentary 'Ayn Rand & the Philosophy of Atlas Shrugged'.
