It is a hard thing to have to review Part Three of a four-part series without having seen Parts One and Two. There is bound to be a certain unclarity as to what has happened before and how the characters relate to each other, because the beginning setups are not there, and since the movie ends when it is only three-quarters done, there can be no satisfactory closure. Even those who thought The Empire Strikes Back was the best of the Star Wars trilogy had to admit that.
American Hustle is an old-fashioned intrigue comedy in the tradition of The Sting, but with more concentration on complications of plot, as smart crooks eventually outsmart themselves-- if you read the story that way.
It starts with Christian Bale in charge of a fair-sized scam, and then his partner, Amy Adams, more or less takes over, and then a rather dubious FBI man played by Bradley Cooper gets involved, and from there we proceed to complications that eventually pretty much left me behind.
