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.
I'm not saying every screenwriter must live in Los Angeles. I'm saying every TELEVISION writer must live in Los Angeles. Until you bite the bullet and move, you WILL NOT BREAK INTO TV.
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.
