I recently saw "American Hustle," which was a very nice change of pace from the usual crap superhero/comic/big-budget sci-fit shit we usually see. The writing was superb, with good jokes and realistic dialogue, the direction also great, and the acting was even better, and while all of the cast's performances were quite good, Christian Bale and Jennifer Lawrence did especially good jobs at portraying their very different characters, in my personal opinion. Bale portrayed a wise con man who carefully views each situation to measure the gain to the risks, unlike his overexcitable fed partner who jumps at every exciting oportunity, and Lawrence being his certifiably insane almost-ex-wife who likes "to put metal in the science oven." But every actor did a great job, making the characters very relatable, and making you care about them and the story in a way that I haven't felt for many movies.
Since I wasn't alive in the 70s, I can't speak for the costumes they used, but, according to my parents, they were dead-on with the fashion style at that time, making the movie feel as though it were really from the 70s. They even went so far as to use the old Skippy's label for the peanut butter jar that one of the characters spreads on his toast.
I'm quite glad my family decided to watch this instead of The Hobbit, which my classmates are still getting orgasms over.
