Saw it last week.
Enjoyed it. Good cast and a typical early J G Ballard plotline. Especially good is the 1970s 'feel' - from clothes, hairstyles, cars and food to the language. It is probably riding on Tom Hiddleston's recent fame in The Night Manager. He is excellent, but there are some other stand-out performances too - Jeremy Irons, Sienna Miller, Keeley Hawes.
