Aside from Lewis's excellent acting, there's little reason to spend two hours with Keane.

Lewis makes Keane's paranoia our paranoia. Kerrigan limits our world to his world. And that's how this grimly shot, roughly felt drama pulls us in.

A small wonder of a minimalist morality tale.

When it comes to an emotional payoff at the end, unlike most Hollywood films, it has earned it.

The role of Keane is a tall order, as he's onscreen for every frame of the film, but Lewis is just brilliant, holding our attention and ultimately our compassion for a deeply troubled man.

Affliction has rarely been so sensitively explored.

A psycho-underworld tour de force like Irreversible or The Machinist, impressive as far as it goes (not far), single-minded but without enough on its mind, a gimmick flick.

The entire second half of the film...is unbearably tense....Lewis, whose performance is the overwhelming center of the piece, deserves a large share of the credit for making the entire thing so grueling.

Lodge Kerrigan is one of the great, though largely unheralded, filmmakers of our time.

It's in that breathtaking humanism, its illustration of the way we connect to one another, and how brittle that social fabric can be, that the film touches on sublimity.
