From NetFlix:

Based on Kazuo Ishiguro’s acclaimed novel, this sci-fi drama from director Mark Romanek is centered on thirtysomething Kathy (Carey Mulligan), who reflects on her time spent at Hailsham, an English boarding school, alongside classmates Ruth (Keira Knightley) and Tommy (Andrew Garfield). Born for an unusual reason, the three struggle with their destiny and their love triangle. Charlotte Rampling plays headmistress Miss Emily.

Until I reached approximately page 72 of Ishiguro’s novel I could only suspect what was happening. Since I don’t do spoilers, you will have to wait (if you haven’t already guessed) until one of the characters gives us the insidious answer. If you can’t stand the suspense then you can find the answer in the Wikipedia article.

In order for the story to work you must suspend much disbelief. Quiet, understated, beautiful scenery, beautiful children, handsome young adults are the hallmark of the film. But there could be no rebellion for the story to succeed. You have to believe that what is happening is now completely accepted by the rest of the world. You have to believe that the progress of the story is inevitable.

It is quite possible that many of you will be bored to death. Slow and politely quiet as a whisper, expect no action whatsoever. “Sci-fi” is a just plain incorrect description. Quite possibly you will find the entire film grim.

Personally I loved the film and thought the ending achingly sad.
