As a preface, note that I have never read the book series and have but a cursory knowledge of them so I came into this film with a pretty clean slate from an expectations perspective. I'll also say that I have some general bias towards the director, Alex Garland, if for nothing other than his work on Ex Machina. For me he is a novelist turned director that is exceptionally good at advancing a story without forcing too much, a rarity for a lot of fantasy/sci-fi directors.
I thoroughly enjoyed the movie (as did my wife), I thought the visuals were stunning, the audio was incredibly immersive and powerful (a big reason to see this in the theater vs at home), and the acting/casting was on point. Annihilation did something that few movies do for me, I felt incredibly small and insignificant, the scale of it all was impressive. There was the real sense of being completely overwhelmed that I think was captured and conveyed really well.
There is something immensely captivating about the destruction that we witness. In going back to look up the books after I had seen the film, I read this line from Jeff VanderMeer's novel:
Annihilation spends the length of the film showing this idea to you, constantly and in a multitude of ways. It explores our own self-destruction, both as individuals and as a people, in a way that is both disturbing and empathetic.When you see beauty in desolation it changes something inside you
There were a few parts that didn't do to well for me (in case you thought I only saw good). I thought the time loss part right after they entered the Shimmer felt a bit out of place. Maybe it was supposed to be some kind of play to disorient the viewer or prepare them for the idea that not all was as it seemed, but it fell flat with me. I also thought there was at least a few times when characters' motivations were unclear. Perhaps that can be chalked up to the changes that the Shimmer inflicts on people, but I didn't read that in the initial watching, it is reconciling after the fact.
Biggest spoiler below (highlight to see):
What 100% sold me on the movie though was the scene towards the end that features Portman in a mirror like dance with her faceless self. Watching Portman stuck in lock step with her double, trapped in a round that inevitably turns violent was an amazing summarization of the film without a single word said. If there are any other modern dance followers, the scene was actually choreographed by Bobbi Jene Smith and I doubt that there is anyone better to capture the rawness and violence that was shared while still being beautiful.
ETA: I know it is early days still but if anyone else has seen the film I'd be very interested in your thoughts.
