The magic science irritated me immensely in a lot of RTD-written episodes, particularly series finales: he seemed to rely on the Doctor speaking pseudoscientific gobbledegook extremely quickly as a deus ex machina far too often. At least Moffat seems to introduce scientifically dubious concepts (such as the isomorphic controls and the clouds responding to singing) early in the episode, so that when he needs them at the end of the episode, I don't feel cheated.
