Fight Club trailer

Fight Club is advertised as a heart-racing thrill ride. Is this different to the reality of the film itself? The voiceover describes the narrator as "tired of his job, sick of his stuff, looking for something new. But he wasn't ready for what he found." The trailer accentuates the action elements of the film. In reality the film subverts the generic conventions of an action film and is something a lot darker and more disturbing.
