Samus Aran is a human being.
Samus Aran is not a person. Samus Aran is an implacable suit of armor with an undying hatred of Space Pirates. Expecting more than that is how you get Other M. Connecting to Samus is neither something that should be possible nor should it be attempted. The story of Samus is one best conveyed through setting and reaction to the implacable, unstoppable object that is Samus.
Samus should be the silent antagonist to a protagonist group of Space Pirates. She should kill them, destroy their work, hunt them down with a merciless, silent gaze.
A movie of Samus should be a horror movie where she is the thing that drags the main characters kicking and screaming from view.
