Why is this film not a classic

Rating: 8/10 (19 October 2016)

I came across this movie led by the hands of Robert McKee, who referenced to it several times in his book Story. The screenplay was flawless, it was a happy ending just like expected, and the action scene was fabulous. Not like other 80s movies, Die Hard didn't mess up my suspension of disbelief at all.
I wonder if anyone notice that only one innocent guy died in this film, and he was Asian. Two guys supported John selflessly outside the building, and they were both African American. Holly McClane was without dispute the heroine, and she was under the protection and mercy of men throughout the whole film, or she wouldn't come out without scratches. The racial and gender hierarchy was pretty obvious, the African Americans are always faithful servants to the white, the Asians are irrelevant and OK to ignore, the white female characters are innocent and weak and in constant need for male protection.
According to Robert Mckee, although in ideal state art and politics are completely separated, in real life they can't keep their hands off each other. Despite its fluent editing, perfect balance between the use of medium shots, close-ups, establishing shots; excellent acting, lenient budget and a really good story, the block between Die Hard and a classic is its core of a cowboy adventure that has faded from the stage of attention through the evolution of gender and racial equity. People's love for a privileged white guy kicks asses and saves lives is dying, and their memory for this skyscraper version of cowboy movie will die with it.
