12 Most Hopeless Sci-Fi Movie Endings

Never Let Me Go is depressing from the very beginning all the way until the bitter end. It's truly awful.

The movie, based on the book by Kazuo Ishiguro, follows the lives of three young adults, Kathy (Carey Mulligan), Tommy (Andrew Garfield) and Ruth (Keira Knightley). It is then revealed that the "young adults" are actually clones that have been bred as organ donors for the rich. Dark, right?

To make things worse, the three are raised together from birth so obviously they become extremely close. Eventually, Ruth and Tommy get together, even though Tommy secretly likes Kathy and Kathy secretly likes him back.

Soon enough the clones are ready to be used and Kathy ends up moving on somewhere else. A decade later she meets up with Ruth and Tommy only this time they have been harvested beyond recognition. Not long after, Ruth dies after her liver is needed elsewhere and Kathy and Tommy finally get to be together.

But, this is no romantic drama not by any means. Tommy dies after having another vital organ removed and Kathy tells the audience that her own organ giving journey is now likely to start.

The scariest thing about this movie is that the premise is not that difficult to believe. Surely, once humans do start being cloned it will only be a matter of time before some capitalism takes hold and does the same thing. Who knows maybe they already are...?
