Something that's just been going through my mind is that several people watching the film end up feeling quite sorry for the boy. People are reading into the story that the dad is neglecting the child rather than the dad being tired having just got in from work (or something to that effect). Are there any shortcuts to establish a relationship that makes the dad look more caring and overworked than lazy? Also, are there more ways of making this kid less likeable without changing his physique (so, no suggestions for make him fatter)
Ideally, not looking for a major overhaul but will take all opinions into consideration.
