What does it mean to be human? Is it woven into our DNA, hardcoded in rows of As and Gs and Cs and Ts? And what makes our genes special, unlike those of, say, a shark or a deer or a tree? Annihilation seeks to answer these questions, while simultaneously answering none of them. Instead, it simply offers different perspectives on the nature of the crazy series of coincidences that lead to sentient life, on a platter of shiny purple CGI. With mostly decent acting. But somehow, it worms it way into your brain, and it won’t let go. It sticks with you, gripping with its shiny purple hands. And for the effect it leaves you with when you walk out alone, Annihilation is more than worth seeing.
