Penn felt bad but his wife convinced him that what he had done hasn't been wrong?! Then at the end of the movie we see Sean Penn seeing Kevin Bacon from a far distance and Kevin makes a gesture as 'you are going down' or something to that effect to Penn. That made me feel slightly better about the ending, nevertheless it was a disturbing drama almost the same as House of sand and fog. You wouldn't feel good or even okay after watching this movie. Penn was really awesome as he was in 21 grams, but I like the theme and the story of 21 grams much better. It was brilliant.
