A few of the lines do not age well, but otherwise a triumph.
Casino Royale ushers in a decidedly new era of Bond. He's rough around the edges, fights dirty, and doesn't always, or should I say rarely, has the upper hand. His interactions with Vesper (who is absolutely amazing) are as charming as they are disarming: "There are dinner jackets and dinner jackets; this is the latter." Wow.
One of best Bond films yet.
