What the fuck is the BBC's problem? Seriously, why not release a damn trailer? The UK fans deserve it because they pay for the show. Fans all over the world deserve it because without us there wouldn't BE a damn show.
It's a trailer. It serves to get the fans of your show excited. What is the damn problem with releasing it? I am so sick and tired of this secrecy stuff that surrounds Doctor Who. It makes no sense.
