Doctor: 'Rosita? Good name. Hello, Rosita.' Christmas is traditionally a time where Nu-Who goes mental with the special effects. Christmas episodes are not your average episode: they're bigger, brasher, littered with innuendo and for the most part, incredibly entertaining. True, some people are turned off by the over the top production (which does occasionally have a nasty habit of getting in the way of the story), but only a fool would deny that they're a stonkingly good romp.
