Many of the reviews are nothing short of hyperbole: "visually stunning and deeply disturbing: very freaky, very scary and very erotic" (in my opinion, none of these adjectives apply), "grippingly eerie, intriguing and unsettling film" (nah, not really...) or even "masterpiece" (yeah...right).
Here are the adjectives I would use: pretentious, drab, moody (in a teenager kind of way), vacuous, directionless, mildly disturbing. You might have guessed by now that I did not rate this movie. Nor do many it seems: the cinema had about 4 people in it. So do not bother, unless you are a total fan of Scarlett and have to see all of her films.
I think the underlying theme for me is one of desperation: this is a film about people (and aliens) driven to desperate acts, as symbolised in the beach scene. In management circles there is much talk about creating 'burning platforms' in order to generate the energy and creativity to achieve transformation. I can buy into a much of this idea and have seen it happen. However, leaders need to take great care: urgency can easily descend into desperation. The consequences then may be anything but creative or transformational.
If you are a leader intent upon setting the platform alight, do you (at least) know where the fire exits are?
