Stylish production, but overly so, to the point of being cartoonish. The characters seem to be aware they are in a period noir drama. Riley's role is a caricature, all fedora and husky voice. The breathy whisper he employs is almost laughable. When adopted by much of the cast it would make you weep. Listen, I know secret police are naturally secretive, but it helps if we, the audience, can hear what they're saying. Once again, a drama that alienates the viewer by excluding them from the dialogue. The broad sweep of the story is interesting and may hold up over time, but I think it would work better if all dialogue was subtitled.
