* BrokenBase: Considered the best by some for its cast of kaiju and nonstop action. Considered the worst by some for its focus on the humans instead of the kaiju and the action instead of the story.
* CompleteMonster: The alien enemy X is a LargeHam who has a VillainousBreakdown after each of his monsters die, but that doesn't hide just how evil he is. [[BigBad The Controller]] wanted to take Earth peacefully and was simply a WellIntentionedExtremist trying to save his people. [[TheStarscream X offs him the moment he gets the chance]] and takes over, instantly letting loose his army of monsters and begins the destruction of human civilization. While many alien invaders in Godzilla movies have done just that, it's the sadistic glee present in X as he watches the horror he's unleashed that makes it clear that, unlike his more peaceful predecessor, he's a sadist who enjoys what he's doing! When he captures the Gotengo at the climax of the film, he orders his men to ''slaughter the crew except the ones he wanted personally''. Where his predecessor took prisoners even when he could've simply let the victim die, X has absolutely no regard for life at all. During the FinalBattle of the film, he takes his time to enjoy the CurbstompBattle he's inflicting on his opponent.
* GodModeSue: Godzilla borders on this for most of the movie, effortlessly wiping the floor with all the other monsters, including powerful ones (Hedorah nearly ''killed'' Godzilla in his original appearance). Horrifically subverted in the finale.
* MoralEventHorizon: X crosses it when he shoots the Controller and then gives the rest of the planet a lecture on how they are cattle.
