I thought it was pretty dreadful. The pace is very slow, much of the minimal dialogue mumbled, and the lighting so gloomy. Juliette Binoche plays an almost comically crazy doctor, throwing around her improbably long hair and sitting on a Sybian sex toy and Pattinson for her enjoyment. The characters are sketchy, the inevitable killing-off unsurprising. The only death that puzzled me was the black guy, who somehow laid himself down on the dirt and became instant compost...? I fell asleep more than once, my husband dropped off about ten minutes in. There is absolutely no empathy or connection with any of the characters, I only stuck around to see how things would end.
They did get the black hole right though - that was impressive.
