At least the industry gave us the respect to address some of the biggest slaps in the face. Now information about the writer will included in press materials so there shouldn't be as many articles written about a movie in which the writer's name isn't mentioned. The public will hear more about the writer's contribution. The director has to at least meet with the writer before automatically firing that one and hiring a different one.
Writers can be on the set for the cast read-through.
And because the writer's name will be on the call sheet with cast and crew, it won't be as easy for those writing invitations and such to forget the writer. The issue of the vanity credit wasn't settled, but it will be discussed more among the guilds, and the public's consciousness about it has already been raised a bit. I feel pretty good about the whole thing.
