The scenery (The Tetons); the characters; the plot (a classic Western - good guy comes to town, lives with a deserving, wonderful family); classic struggle, good vs. evil; great gunfight scenes; after righting all wrongs, good guy gives young boy a credo to live by and up to; good guy exits in super scene. It was the Western to end all Westerns! In various forms and scripts it has been imitated but never equalled or surpassed.
