Not good. I'm not blaming the actors, but the writing is awful. Things like a baby on a conveyor about to be eaten by whatever alien. Or, Maestro, who simply makes no sense as a character, or as a plot. The Doctor doesn't know what to do??? He's not just running scared? Being chased by the alien "of the day"? That's not the same Doctor that we, the audience, somehow knew that he knew something. Otherwise, it's just one chase scene after another. I am quickly growing BORED of this season.
