It's good, but too fictionalized
I liked this movie, but I wish more of it was true to fact instead of what it is. Holliday didn't die at the OK Corral in real life. John Ford had met Wyatt Earp and supposedly portrays an accurate depiction of the shoot out, but I feel like he took advantage of the valuable information since it was written in the script that Holliday dies, when in reality, Holliday dies of TB some years later in bed. It is a really interesting story, and I love Fonda's performance, but I feel like it would be better if it were based more on the actual events. Also, they should have changed the title when the part of Clementine was drastically cut. She's hardly in the film. I do recommend it for entertainment value though, but don't rely on it for any biographical information.
