He was good for the role and mood of the film IMO, same as Arnold is good in many of his roles despite not being a great thespian of the screen. Seems Connor was seeking to be "the one" primarily out of a sense of duty--keeping Kurgan from winning the "prize," and perhaps knowing he was the only one who could achieve that goal. A man driven by the burden of that duty despite the fact that he didn't particularly enjoy life makes for good drama IMO.
