Script review - "Bubbles"

This has a fantastic idea, or at least what sounds to be a fantastic idea - a biopic of Michael Jackson's chimp Bubbles. He's an eyewitness to various highlights of Jacko's life - huge fame, weirdness, child abuse allegations. Problem is after a while it begins to be a bit dull - Bubbles is a watcher, passive for most. I'm not sure how else you'd do it - maybe got a bit more nuts and inventive.
