"The King's Speech" is an enjoyable movie. The performances were excellent. The term "mature" comes to mind. The movie demonstrates that special effects are not always the singular factor for success.
The grave atmosphere of a coming war and all the horror that this entails was captured by the performances of the cast. To be sure, this atmosphere is what elevates a perhaps trivial event into an important one. The king represents the nation and cannot be seen by the world as weak and deformed.. This important struggle was captured by the film and exemplifies why the heroic is always important.
