Mel Gibson has made a lot of films where he’s the simple-minded tough guy, notably the Lethal Weapon series, but the last few years have seen his personal life overshadow his career, as he careened from one gaffe to the next. Edge of Darkness represents him trying to get back into the groove, to recover his acting career, and it’s an exciting but distressingly formulaic film.
In a strange nod to The Sixth Sense, Tom constantly talks with dead people too, once his mother, but mostly Emma. As the viewer, it was disconcerting because Emma would show up in scenes and reveal a critical observation, then vanish again after he acknowledges her existence. It often made Tom seem more like a homeless person, particularly in one scene at a public park where he’s dressed in a long raincoat and sits on a bench talking “to Emma”.
