This is strictly Hollywood. If one reads even the most fundamental biographies of the Earps and their associates, we come to realize that their feud with the Clantons is overblown by writers who wished to satisfy an audience. The Earps and Doc Holliday were far from perfect enforcer's of the law. Wyatt was as much a politician as he was a lawman, having on many occasions to try to appease a population that didn't especially like him. Doc Holliday was a user and abuser and a very sick man. The Earp brother had their own problems. One of the foibles, especially of Wyatt, was being bad judges of women. This film makes them saviors and, in the Western tradition, black and white. The shootout is a lot of fun as is the suspense leading up to it. It's certainly not a biopic, but it's a really fun Western.
