This is the most honest depiction of Las Vegas, especially of the time period it was portrayed in. Every time I watch this picture I fall in love with it all over again. I never thought Pesci would be able to top his dynamic performance in Raging Bull until I saw Casino. The art direction is splendid, most likely the best of any film Scorsese has ever done. The film deals with a particular time period and a particular atmosphere and accomplishes an overwhelming achievement by creating and accurately portraying both. I would also venture to say that this is probably his most ambitious film.
Along with Mean Streets Casino is probably Scorsese's most underrated and unheralded picture. If you haven't seen Casino yet, stop whatever it is you're doing, rush to the nearest video store, rent it, and watch it.
