Only afterwards did I realise this was not the film about people getting off on car crashes. I've seen this film during a Pathé Oscar weekend, and remember being slightly disturbed by it.
Watching it again, things came back, but being in America, close to the neighbourhoods and streets of this film, brought a very uneasy tension to the surface.
Positively did not want to get into a car after watching it, but it must be said that the general mood before putting this film on, wasn't one with much happiness to start with.
