'Never let me go', at the weekend. I hadn't read the book, so had full benefit of the creeping realisation of what was happening. Deeply disturbing.
Was it good? I read the book last year and found myself increasingly frustrated at the FAIL of the science to the detriment of my enjoyment. 
The science is largely unexplained, other than a reference right at the start to a medical breakthrough that took place in 1952. It's all seen from the viewpoint of the main characters, for whom there's no choice - other than a possible deferral of the inevitable. Someone said afterwards - why didn't they just run away? But the details of tagging, medication & control are left mainly to the imagination.
It's more of a 'what if' story, in which scientific accuracy / plausibility is less important than the relationships & the morality of what society chooses to do. The science might have been stretched but - given that it's fiction - I didn't think it was too unbelievable.
So yes, I thought it was very good. But I'd naively assumed that it was a just trad love triangle story of 3 children at boarding school and their later relationships as adults, so it came as something of a surprise. Of the 5 of us who went, 2 had read the book (apparently it's standard book group fare) and both enjoyed the film.
