The latest science fiction thriller by the extraordinary Alex Garland is definitely not going to be for everyone. It is a massive risk taker whose results will enchant or alienate any that watch it. This review is for those who have watched it, so you can either relive the experience, or perhaps see why some critics and viewers are obsessed with what is being called a very different film. Here is my take on Annihilation, and why it is sensational. Of course, be aware that there are fully descriptive spoilers ahead.
