Enjoyable hokum shot through with black humour. Great snapshot of 70s London. Tame by today's standards but markedly more explicit than Psycho could've been, as if here Hitchcock can finally give reign to his criminal and erotic obsessions. The plot stretches belief, much like a giallo. Great last few minutes.
Another fantastic Adam Curtis film - he is like the David Attenborough of political documentaries on acid, with a voice that often comes across as a parody, as if Brass Eye is narrating. Thought provoking meandering rabbit holes are provided that go down here and pop up there, with it all seemingly coming together.
