It's weird what Dick Jones did to Ronny Cox's career. Before that role, he was consistently typecast as nice, sweet, agreeable guys. Getting the villain gig in RoboCop was a major departure for him. But ever since then, he's been typecast as the most awful, nasty guy around. And I think that's affected how people have perceived (and written) Jellico. Cox played him as a character in between his old nice-guy image and his modern mean-guy image, someone who had a mix of both, but that mean-guy image so dominates people's perception of Cox these days that it affects their perception of Jellico as a character and they only see the mean side.
