Austin Powers paid tribute to the third Bond film with the title of its third film, Goldmember. But that franchise was ready to roll over and die by the time it reached number three. Goldfinger, by contrast, is widely regarded as the defining film of the Bond franchise. In fact, Peter Travers of Rolling Stone named Goldfinger the best Bond film ever.
So what makes it so good? Well, it defined what makes Bond Bond, and it set the bar high for its key elements—girls, gadgets, and a killer song. Pussy Galore is on Vogue's list of "Top 10 Most Powerful Bond Girls of All Time." Shirley Bassey's "Goldfinger" is Rolling Stone's #1 Bond song.
And as for cars, Goldfinger features the first appearance of Bond's Aston Martin DB5, tricked out with so many gadgets that it's basically the Swiss Army Knife of cars. This car even appeared in more recent Bond films like Skyfall and Spectre.
Yep, even the new Bond films are fanboys of this one.
