You don;t sue the creators of the show, they have nothing to do with publicity, I mean sue the people in charge of advertising who keep saying SEASON finale. The creators don;t have anyting to do with advertising and if they DID do a last second change o mind they were probably blindsided too.
But it's still false advertising to p[ull a stunt like that...isn;t it?
To be honest, I wished they would show Phineas and Ferb's lives after they get older. But, as is the situation, that probably won't happen. I can understand your frustration, but you know, being optimistic is apparently the only way to be happy. I heard you can mail Disney. Do you send it in a traditional way or do they have an email address?
