You can have good writing, but a great actor will make it feel and sound like great writing. You can have great writing, and mediocre actors will make it feel mediocre. Without the actors, you have nothing.
Everything you listen to when you are 17 should be embarrassing, otherwise you are way too cool.
And the inner dynamics of Hollywood are like politics. Say you give a script to a group of executives - they all sit around, afraid to voice an opinion, saying nothing, waiting to know what the consensus is. Just like focus groups, opinion polls or a cabinet.
