The big 'but' is what did all those brilliant actors make of their raw material, the script and the screenplay?
Please let me express dismay that this is still such a 'live' (difficult choice of a word) topic in the UK, with the whole Esther Rantzen story on the lips of the nation, a much-loved TV star facing a dismal death from cancer, and unable to choose to die with dignity. Please also let me say that I live elsewhere, in the State of Western Australia, where Voluntary Assisted Dying is on the law book, as it is in all of the other five states of our nation, and has been for so long that nobody even thinks about it any more.
The UK is not so enlightened, and those people who consider that their personal religious affiliations give them a right to insist on how others live their lives, and how they die, still appear to hold sway. We had that battle here about five years ago, not long after I was myself diagnosed with cancer, and this is a matter of considerable comfort to me, knowing that a slow, lingering, agonising death will not be something I will be forced to endure if that time ever comes.
There's the background setting. I wish to avoid spoilers, as such reviews which are thus blanked tend not to get read. I will simply say that those involved do not display in any way the competence we would associate with them from their former professional lives. A top-ranking police officer and an SAS officer in particular would plan things immaculately, and carry them out faultlessly. It is the fact that they don't even get close to either which spreads this out across six episodes, the last of which was all but pointless.
Perhaps they felt they had to do things this way to present a 'balanced' view of Voluntary Assisted Dying, and maybe the religious obstructionists would have otherwise been even more up-in-arms than I am sure they were.
So they did all this to generate drama, and thus lost the plot.
8/10 for the courage to at least open up this dialogue on such a vital topic, and for great acting, but ...........................
