Annihilation - 2018 - 6/10

Extraterrestrial object impacts isolated southern USA coast.
Flora and fauna soon begin to alter, then the affected area begins to widen.
A select team of four women cross into this zone, also known as the Shimmer.
Previous male units vanished with one exception.
Taut SciFi thriller packs in suspense, psychological drama, mystery and a creeping sense of unease.

I went into this stone cold, never having read the runaway bestseller upon which it is based.
While some reviews cast this as an invasion film, it is a contagion story, unless contrary details are in the book.
Themes of adaptation, assimilation and utter indifference may confuse “answer seekers.”
Visuals are imaginative, sound mix is unobtrusive, acting is fine.
For all that, this struck me as a left turn fork of Day Of The Triffids.
Afterward, I had an odd reflection - that may only resonate with Southerners - as I wondered if the author had grown up in a pre-kudzu era, before the landscape was overwhelmed, and if the Shimmer is an echo of that.
