I just have to ask, why do you hate sony so much? I never see you say anything good about anything sony.
Also he is one of the most unique video characters around.
Sure he is bald so what. How many people have the ashes of their family attached to their skin? So generic right?
Kratos is a very emotionally complex person. Everyday he must live with he fact that he killed his family. Every day he must live with the rage of what the gods did to him. He searches for something that will allow him to forget his past. How many of us can say we don't want to forget things of our past?
Also more about his design. First off he is a white greek person with the facial features found mostly in people of African decent. That is pretty unique right there too. Normally if a person is white in a game, they are all white. Black they are all black. However he is not.
Also, how many people would not be "only brutal" in combat in a war where everything is trying to kill you? Ever seen First Blood? I am sure you would think rambo is just as shallow in that movie and not watch it. But oh look he cries at the end. You have to KNOW the story to see how complex someone is. Looking at some gifs of him KILLING STUFF wont tell you anything about his emotions.
tldr: Fanboy. You never even gave him a chance because you hate sony. Good day.
