Yes, there are folks out there with "fresh" ideas the problem is Hollywood has become a thing worse than a "good ole boy's club" it has become a pyramid of familial associations and unless you are either directly related or brought in via marriage, chances are close to nil that your ideas will ever get tabled and even at that, you must cow down to whichever iron hands are out there. A great example is how Cameron managed to force
M. Night Shyamalan to remove the proper title from the new film "Last of the Air Benders" film in which AVATAR is the established prefix.
The rule of thumb in Hollywood and much of American Show Biz these days is that being a part of an established show biz family is the ultimate ace up one's sleeve. Having a significant level of fluid economic backing (or personal wealth) is the second major trump in that most "celebrities" of the past generation bought and paid for said status... just look at Tv & film credits and you'll seen numerous instances in which the star of the show is the executive producer and/or similar management level influence. It is a common fact in the Film, Television and live show mediums. Next in line is to be Jewish... I'm not being antisemitic here, it's simply a fact that Jews & Catholics tend to dominate the industry followed by the "minority" card... I'm not talking as much about "race" as I am the current "flavor of the month" i.e. gays/lesbians, blacks or the current trend tied to Latinos/Hispanics... this is a category that is influenced significantly by the social-political atmosphere of the nation.
So as they said in the 80s, in order to "make it" in Hollywood you must be the Lesbian child of a Catholic & Jewish parentage who are likewise black & Hispanic or, if possible Native American and partners in a Casino...
