I watched the movie immediately upon its release on N.....x and without having read any reviews first on IMDb. My motivation was the media hype and in particular, high expectations of another stellar performance by Sandra Bullock after her spectacular role in Gravity. Not. I was not as much upset about her below radar appearance as stealthy as the invisible beings, most stars have one of those lapses in their acting careers, than by the storyline so full of holes envied by makers of Swiss cheese. I struggled to comprehend the logic in one scene after another, to numerous to cite, that early into the painfully long script I just resigned myself to enjoy the acting. I patiently waited for Sandra to captivate me and take me along for a suspenseful ride instead of those birds, but at the end felt trapped as much as them in a black box, not seeing anything, just sensing a strange presence of something inexplicable. And that's the point, how to explain such a movie that should never have been made.
