Similar in ways to existenz and videodrome themes. Really been missing David Cronenberg as he hasnt made many movies recently, so glad to see his sons taken over. His films are getting much better, this one being my favourite by miles so far. Excellent use of London set, nice camera work and its a real gorefest. It doesnt hold back in that respect, and some of the visual dream sequences were 1st class. Its not a perfect film by any means but has a number of strengths that horror film fans will appreciate.
