My wife and I have been watching episodes of Have Gun Will Travel, the classic Western TV drama. The hero is Palladin, a professional gunfighter who rents his talents for pay while following his own code of ethics. The first 2 seasons are available on DVD. Some of the episodes are written by Gene Roddenberry, the creator of Star Trek. In fact, he served as head writer on the show.
We watched one of the episodes he wrote tonight. In classic Roddenberry fashion, the show began in the middle of the story, had a fair amount of action, and took the moral high ground.
Still, there's no confusing the hero of this show with Roddenberry's later heroes.
He has a horse,
Without warp drive.
