That was only a third of the way through. The rest of the movie hinged on the rather lame premise that the girl has fallen in love with The Man of Steel, despite having participated in the murder of his brother, and this makes Eric mucho jealous. So Eric shadows them as they fall in love and get married and have a child. All along Superman is still wondering just exactly why his brother was brutally murdered, so he hires a detective, and he really isn't too pleased when he finds out that his wife first screwed the brother and then set up his death. That's gotta hurt.
Years go by.
They resolve it somehow, but I can't say how. I wouldn't want to spoil the ending for you. Actually the ending is OK, as were the first thirty minutes. The other hour seemed longer than the Hundred Years War. The other woman was in an equally dark scene, but had an unimportant role.
