If you want to grab an agent or executive's attention, your script doesn’t need to be as good as professionally written scripts … it needs to be BETTER than professionally written scripts.
Don't blame writers for a dearth of originality. They're busy writing, developing, and pitching the most creative, engaging stories they can... but they don't get to decide whether those stories get made.
If you want to get your pilot to producers, agents, or executives, the only thing you can do is move to Los Angeles. I know you can find script consultants, books, seminars, or agents who tell you otherwise, but THOSE PEOPLE ARE LYING.
