* AnticlimaxBoss: The governor. [[ImplacableMan Reza on the other hand]]...
* SugarWiki/AwesomeMusic: Music/EnnioMorricone at his usual finest throughout--albeit with a rather "trippy" twist. It's worth noting the score has often received more recognition than the actual movie.
* CompleteMonster: {{Colonel|Badass}} GŁnther "Gutierez" [[TheHeavy Reza]] is a [[SilentAntagonist silent villain]] who, throughout the movie, doesn't express a single emotion beyond self-satisfaction. He [[ColdBloodedTorture tortures Dr. Villega]] into identifying various members of a crowd as revolutionaries, then has them shot in front of him, smiling a little wider with each body that hits the ground. He's also the man responsible for the deaths of Juan's children and father, singlehandedly [[KnightOfCerebus causes the film to shift]] from BlackComedy to serious drama, leads an army ([[ANaziByAnyOtherName based on Italian fascist stormtroopers]]) that seems intent on [[SociopathicSoldier killing or imprisoning everyone they meet]], and in the climax, guns down [[spoiler:Mallory]] [[InTheBack from behind]]. This, coupled with his ImplacableMan status makes him utterly terrifying.
* EarWorm: "Sean-Sean...Sean-Sean..."
* EndingFatigue
* MoralEventHorizon: Colonel Reza and the Mexican army cross it with the [[spoiler:murder of Juan's children.]]
* {{Narm}}: Despite EnnioMorricone delivering his typical AwesomeMusic...the "Sean-Sean" song can ''really'' ruin the moment with just how ''trippy'' it is!
* OvershadowedByAwesome: Has the misfortune of falling in between two of Leone's most celebrated films.
