Scorcese seems to have several different directing styles, and Casino follows in the tradition of Goodfellas as a pseudo-documentary. Scorcese's normal supporting cast are also involved in this film, including his great mother - even though she usually has incredibly minimal roles, they are always memorable.
As the viewer, you can't stand her, but that is the point. Robert DeNiro and Joe Pesci are both fantastic in their roles, and Sharon Stone actually turned out a non-irritating performance. Rothstein is a complicated figure in that he is not a heavy, yet he wields a lot of power due to the respect he has gained from his mob bosses back home. Along the way, he marries a drug-addicted con-artist trophy wife (Sharon Stone) and struggles with his friendship with loose-cannon Nicky Santoro (Joe Pesci). Robert DeNiro plays Ace Rothstein, a fantastic bookie who is chosen to run the Tangiers hotel and casino. Casino spans three decades and chronicles the true story of a faction of the mob who ran Las Vegas casinos. Even his lesser-known or critically panned films are above the 'great film' line, and Casino is certainly no exception. I have to admit my bias, because I believe that Scorcese cannot do wrong - ever.
