I saw a lot of reviews not liking the ending. I thought the end was one of the most brilliant jokes in the movie, everyone has seen over and over a situation movie like this where after the crime there's a lot of twists and turns where it always seems the criminals are on the edge of getting caught. In this movie's world the horrible behavior of everyone is excused because of what a nasty person Ward's wife was. So the easy scott free get away ending made it feel like their actions set the universe right in this mean spirited fun house world and I found that very funny.
