The green mile was a notable movie to me. It contained many dramatic scenes. However, it was not my favorite.
John Coffey was a pure definition of an innocent and kind-hearted human who was unjustly convicted of a horrific crime. Not only this but also he had some kind of special gift. And the reason he was bitterly hated by the people without any official evidence was that he was a black man and at that time people were much more racist. Although John Coffey was a gigantic person, his behavior and character reminded me of a child.
The story is written by Stephen King which I surmise was obvious if you were familiar with his style.
