Mel Gibson turns a grade four movie into a seven. He does this with sheer grit, remarkable intensity, and incredible (especially in a cliche-ridden action flick)consistency. One goes through this movie with him in the same way one went through a Janis Joplin performance--on a very high wire. Certainly memorable--his madness, his beauty, his human-ness (how can we forget all those very personal apologies for his defensive violence). And certainly his toughness, not this canned romance stuff, should have marked the final scene
