Good Movie, but Oscar Nominated?

Rating: 7/10 (8 April 2014)

In 1978, the con man Irving Rosenfeld (Christian Bale) teams up with his lover Sydney Prosser (Amy Adams) that poses of the British Lady Edith Greensly in a scheme of investment from a Londoner bank to swindle desperate people that need money. Irving is married with the futile housewife Rosalyn Rosenfeld (Jennifer Lawrence) and he stays with her because of her son that he has adopted.
Out of the blue, the ambitious FBI agent Richie DiMaso (Bradley Cooper) arrests Edith and he forces Irving to help him to arrest the Mayor Carmine Polito (Jeremy Renner) of Camden, New Jersey. Irving plots a scheme but he befriends Carmine and when he goes to New Jersey, he finds that the Mafia is involved in his plan. When the loudmouth Rosalyn tells to her "boyfriend" Pete Musane (Jack Huston) that is a mobster that Irving has a problem with the IRS and Richie is an agent, Irving need to plot another scheme with Sidney to save their lives.
"American Hustle" is a good movie but not special highlighting the wonderful music score with classics from the 70's. The final twist is predictable and it is funny to see the situation of Richie DiMaso in the end. However the nomination to the Oscar is another absurd promoted by Hollywood. My vote is seven.
Title (Brazil): "Trapaça" ("Swindle")
