That is not the vital point, but it is an added creamy center of pure awesome. Of course, the latest Moffat-penned "Dr Who" episode was actually a huge disappoint to me. A C effort by an A+ student, as someone else put it. Regardless, all of his other Who scripts are AMAZING. "The Doctor Dances/ The Empty Child" is what got me hooked on the show, and it still hasn't been beaten.
Plus, "Coupling" should have been totally annoying, due to the large amount of HILARIOUS GENDER STEREOTYPES!!!! based humor, but somehow it's totally hysterical. British comedic timing helped, but the writing is really kick ass.
In conclusion, in spite of the recent mistake, Moffat still rules.
