The Becket-esque halfway house in which Spider resides has a nearby factory that looms in an almost Ballardian way. The two styles work as one thanks to Cronenberg's ability to make them feel as if they deserve each other.
I really like Miranda Richardson and loved seeing her get such a powerful role.
Be warned, the trailer makes it appear something it's not.
