Query: Guilty pleasure

I really liked this movie in the theater, and yet it's hard to say why because I can't think of too much in particular that really stood out. So for now, I'll recommend (1) Lumet's direction (I'm being a snob--I can't pinpoint why I liked this fact, but his being behind this movie both impressed and surprised me), (2) Johnson's performance, (3) a slam-bang ending that had my friend and me gasping with delight at how far it was willing to go, and (4) one of those moments that can turn an otherwise humdrum movie into a must see -- pay attention to a scene in which Johnson is at a bar and an attractive woman approaches him. What he says in reply to what she says is so good I wish I'd written it.
