When translating a work from page to screen there should be an obligation to be true to the original work.
If you want to change the story, then don't use the same title because you are not telling the same tale.
Tell that to Alan Moore when he turned characters from classic works of literature into sexual and social deviants and had the audacity to try and pretend it was art.
"Spider-Man doesn't have fans. He has people who follow him. Like Jesus. Now I have fans! People who adore and worship every little thing I do or say. Like David Koresh. Or The Jonas Brothers."
