Understandably, when one sets out to make a film about the mentally ill, a chief aim should be to depict the illness in as direct a manner as possible. However, in DFL the illness practically becomes the sole focus, reducing the ill to a collection of tics and mannerisms with no real personality. And while OCD sufferers may actually feel this way, grandiose depictions of our protagonist as the Howard Hughes of London are a bit much. Still, Sheen draws empathy in a tough role; worth watching.
