The internet's effect has been to make the rest of the world feel like the Valley.
The closest thing you could've had to the internet experience, in terms of a gluttonous diet of porn, and movie and music history.... before there was the internet was growing up in the Valley, and that Anything Goes aesthetic that raised Quentin Tarantino, Judd Apatow and others... that embarrassment of riches -- and junk -- meant multiculturalism became a-culturalism, because there's no perspective passed on to you -- just a Hollywood library -- and it can create a cynicism and exhaustion because it burns you out if it's not given a context, or if that's all you ever feasted on.
Regarding the myth of Tarantino working in a video story and seeing everything.... His father had been an actor in Westerns in the 60s, and Tarantino was already a film-fanatic - that's why he was at the video store to begin with. It was correlative, not causative....
Tarantino's sensibilities are Valley even if he technically lived somewhere else in the Los Angeles area. [He did take an full time acting class in Toluca Lake, in Burbank, "the media capital of the world" and an incorporated city within the Valley]. That somewhere else was always just on the outskirts of Hollywood or L.A., it seems, so he was a nose pressed to the window, which ties into the Valley sensibility anyway.
“Kitsch causes two tears to flow in quick succession. The first tear says: How nice to see children running on the grass!
"The second tear says: How nice to be moved, together with all mankind, by children running on the grass!”
So with all these directors [see also Paul Thomas Anderson, Burbank-brat Tim Burton] they were enamored and obsessed with entertainment from an early age, and had a knowledge of "the canon" and even the anti-canon in a way that was hard to pull off pre-broadband. They all had family in the business as well. It's Steely Dan's "Show Biz Kids" about the people who made movies of themselves.
On ILX, years ago, I started a thread where you had to compare a director to a band, aesthetically: Tarantino's band was Pavement. They were both historians of their form, had the same breakout year (1992), and would steal from their idols and reference works every chance they got. They both flatter critics by putting in references that only critics and fellow buffs would appreciate -- they're the ideal artists for cinefiles and record collector geeks in the Nineties and Noughties. It's ultimately all nihilistic because you feel if you took their record collections and films away they'd have nothing important to say. Entertainment about entertainment.
That's the feeling the Valley gives you: entertainment is to it what Catholicism is to Vatican City. In many ways it's just Hollywood with its make-up worn off. Filled with has-beens and up-and-comers. There was a women who, when this friend of mine introduced himself to her and said he was living in North Hollywood, she said "North Hollywood? Are you on your way up or on your way down?"
