10 Mysterious Sci-Fi Films That Gave Nothing Away

10. Annihilation

Annihilation revolves around an anomalous zone called The Shimmer that distorts reality around it. As The Shimmer expands, a scientist called Lena leads a team of explorers to enter The Shimmer to learn its origin and purpose.

Annihilation gives the audience a lot of information but very little of it is concrete. The films deals with suicide, depression, self-destruction, alcoholism, and grief. While these themes are being explored, the characters are being attacked by shark-crocodiles, doppelgängers, and screaming skull-bears. As the cerebral story concludes with Lena embracing her husband, it's unclear whether she is really Lena or a doppelgänger.

Now, you might think you would have better insight on what's happening by reading the book which the film is based on. However, the book is so different, the film barely qualifies as an adaption. In fact, the director, Alex Garland, admitted he didn't re-read the book when he made the film so the story is based on "his memory of the book, not the book itself". In a way, this makes Annihilation better since there is no source that explains the film fully, allowing viewers to draw their own conclusion.
