It's quite pathetic that there wasn't intervention way sooner. If it started in HBP and spilled into DH. You can't tell me that a director and co-workers wouldn't notice their lead was messed up. I am surprised, that it sadly didn't come down to money, a multi million dollar movie franchise and a very highly paid boy on the verge of screwing everything up. He still so young, and back then, younger still. Where were the grown-ups?
