Just making this a separate post to make it searchable. Regarding a character being emotionally detached. Yes, there are real people like that. But:

Even in pure action movies, in the best ones, the character cares. They don?t have to wear it on their sleeves, but they do. I?m not saying, make it a love story. This is were you differentiate between a great movie, maybe a masterpiece and an ok movie, which could maybe attract audience with fancy action sequences and/or?cgi, although, audiences are finally asking for more there, too. The protagonist needs to have an inner life. At least one meaningful relationship. They must feel and care. Maybe not show it much, but care they must.

Because why? You want the audience to care, go on an emotional journey. You want them to feel something. I mean other that woah, that was a cool action scene. Unless you?re fine with a detached audience.
