Mental is madder than madcap. I heard one critic sniff, "It's kind of broad"— and, Your Honor, the defense agrees! But if broad means "unsubtle," it doesn't have to mean "unreal."Mental makes most other movies seem boringly, misleadingly sane.
Why "misleadingly"? Because writer-director P.J. Hogan aims for a tone that's more concentrated in its craziness — and thereby serves up more concentrated truths about human nature.
