I do. The King's Speech portrays Prince Albert/King George as having few substantive moral faults -- his primary faults are issues of emotional functionality rather than moral failures. Which would be fine, except you're talking about the years leading up to World War II -- you can't allude to these issues of deep moral import and then say that the moral makeup of your primary character is somehow irrelevant to the story being told. By whitewashing King George's moral faults, The King's Speech is being dishonest about what kind of a person he was and about what role he played in British history, instead presenting a false image of what kind of man he was in order to fit in with modern ideas about what ought to have been done and to fit in with the low-level cult of personality that helps sustain the British Monarchy.
Queens consort are usually referred to as "the Queen" or "Queen Such-and-such." Indeed, during her time as Queen Consort of the United Kingdom, Elizabeth Bowes-Lyon was formally titled "Her Majesty the Queen."
That article makes it very clear that upon the death of her husband and ascension of her daughter to the throne, she became known as the Queen Mother.
