- Acceptable Targets: Haruo, mostly due to his overly angst personality, and his questionably "heroic" decisions.
- Awesome Music: XAIs White Out featured in both the trailer and the end credits.
- Base-Breaking Character:
- Haruo has divided viewers of the film, with most Western viewers decrying him as an immature and reckless hothead who endangered the lives of those under him for the sake of petty vengeance. Others have had a warmer reception, noting that he had a right to be angry — having grown up in hellish conditions and lost both his biological and foster family, didn't ask any of his soldiers to do anything that he wasn't willing to do himself, that his plan — which he'd throughly researched — ultimately succeeded, and that he gave the order to retreat when the original Godzilla woke up instead of ordering them to attack.
- Godzilla Earth himself, with some fans praising the "nature god" aspect of the character and how he represents an "ultimate evolution" of Godzilla. Others find the design awkward, too derivative of the Legendary version, or too goofy-looking with regards to his face, with his botanical nature very divisive among purists of the series.
- Creepy Awesome: Metphies' constant religious speak and borderline worship of Godzilla is unsettling on its own, but combined with the darker setting, he becomes nightmarishly cool.
- Godzilla Earth himself. For such a hostile and omnicidal creature, he has a strangely calm and gentle appearance that is a disturbing counterpoint to his violent rage.
- Designated Villain: Godzilla Fillius, though this is the point. Everyone treats him with contempt, and not once did he attacked the humans out of spite. He only did so out of self-defense and if he did attack, he would have ended his fight swiftly. After killing Leland, he goes on his way. His father would have held every single person on sight dead-to-rights as soon as he attacked.
- Funny Moments: Even this movie has some funny moments of its own:
Mulu Elu Galu Gu: This is why I hate working with stubborn species.
- In the beginning, they tried making a Mechagodzilla to combat the original, but they couldn't get it to turn on.
- Later on when they went to lure Godzilla:
Adam: So who drew the short straw? (Godzilla looks at him, preparing atomic breath) GUESS IT'S ME!!!
- He Really Can Act: Who expected Chris "Kirbopher" Niosi, the creator of TOME as the protagonist Haruo?
- Hilarious in Hindsight: Godzilla's origin as the next stage of life on Earth, accelerated by nuclear radiation, is exactly the same retconned origin featured for Zilla in the unmade sequel to Tristar's Godzilla film from 1998.
- "Holy Shit!" Quotient: Godzilla is not only massive, he so tall the humans have no choice but to retreat. And that's not all: He has a power breath and a tailwhip that can destroy a mountain. Truly a God Incarnate indeed.
- Jerkass Woobie: Haruo, a vengeful protagonist and crew member of the Aratrum whose so keen on killing Godzilla for driving humanity out of earth and killing his family in a process which is understandable for him to be very vengeful and angry, but doesn't stop from him being a massive Jerkass towards anyone he comes across.
- Memetic Mutation:
- The reveal that this Godzilla will be taller than the last incarnations in Shin Godzilla, whom in turn was taller than the previous incarnation in Godzilla (2014), whom in turn was taller than the previous incarnation in Godzilla: Final Wars; has lead to many jokes amongst G-Fans that the filmmakers are having a competition on who can make the biggest Godzilla.
- The reveal that Godzilla is plant-based has fans reducing it as "Godzilla is a plant". Many compare him to Groot, or make jokes about his dorsal spines being weed leaves.
- Due to Haruo's personality, fans occasionally joked the trilogy only focusing on a very angry, loud & vengeful main protagonist with monsters as guest stars/cameos.
- Moment of Awesome: The set up is one: Expies of the Xilians and Simians come to Earth and team up with humanity to try and stop Godzilla in exchange for taking over the Earth...and Godzilla kicked their tails so hard that all of them have to work together to run away.
- Narm: Some fans find Godzilla Earth's somewhat goofy-looking face awkward, especially given that his the biggest and most powerful Godzilla in the history of the franchise.
- Older Than They Think:
- The concept of a future on a planet ruled by kaiju had previously been used in the IDW Godzilla Cataclysm and Godzilla: Oblivion series as well as the popular fan film, Godzilla x Kaiju Killer.
- One of the human characters having an Ahab-like obsession with killing Godzilla is pretty common in the franchise, with one of the more recent examples of it (up until this film came out) being the IDW comic Godzilla: The Half-Century War.
- Some Anvils Need to Be Dropped:
- A series tradition. And in this case, revenge leads to self-destruction. The film makes note on how Haruo has nothing but revenge in his mind. He's obsessed in killing Godzilla that his comments on how kaiju, especially the God-king, took even the basic human decency, and saying this does make him out a Hypocrite. His own anger and obsession with revenge proved to be his downfall as he was completely unaware the Godzilla he hated so much is nearly invincible, but annihilates his army without trying.
- The path of vengeance is a vicious cycle. Haruo hated Godzilla for the murder of his parents and indirectly, his foster grandfather. However, after killing Godzilla Filius, Godzilla returns to exact his revenge on the humans who murdered his son.
- Tragedy and consequences makes its return in anime form, but its context is played differently here. Haruo lets his own tragedy get the better of his judgement after letting the deaths of his parents and Yuko's grandfather's death become so ingrained in his mind that he allowed revenge to bring out the worst of him. The consequence of killing Godzilla's son not only angers the latter, he succeeds in his own revenge against Haruo's army in one fell swoop.
- Spiritual Adaptation: Given the premise of the movie, this movie is most likely Planet of the Apes, Warhammer 40,000 or Cthulhu Mythos in anime format.
- They Copied It, So It Sucks!: Some fans have accused Godzilla's new design of being a rip-off of Godzilla (2014).
- Unexpected Character: While kaiju like Anguirus, Rodan, and Kamacuras aren't that unexpected due to being staples of the series, Dogora and Dagahra certainly weren't expected since Dogora only appeared in a standalone film, and Daghara is only loosely connected to Godzilla by way of the Rebirth of Mothra films. The prequel novel Monster Apocalypse features even more unexpected monsters, such as Zilla, Varan, Gorosaurus, Gabara, and the Griffon from Latitude Zero.
- Unintentionally Sympathetic: Godzilla himself. He's clearly supposed to be malevolent and dangerous, but we don't actually see him killing anybody before his Non-Malicious Monster son is killed. Given that Fillius was itself Non-malicious, it's not unreasonable for fans to extrapolate that the same may have been true of Godzilla before humans went to war with him. note Not helping is the fact that in both sequels he faces off against far worse evils who are more dangerous than he ever was, or that unlike them, Godzilla is satisfied with humans simply leaving Earth and never coming back.
- Unintentionally Unsympathetic: Though it's really hard to sympathize with Haruo throughout the film despite his parents death at the hands of Godzilla, but considering that it's entirely his fault that nearly everybody dies or in danger when he drag everyone along for his endeavors to take out the kaiju in the first place. In the end it wasn't Godzilla they've killed, it's his son which pissed off the awoken Big G himself.
- Values Dissonance: Some have noted that Haruo — who is determined to kill Godzilla to avenge his parents' deaths and the 22 years of suffering and humiliation that humanity has endured — speaks to Japanese cultural values regarding dignity and honor. Most Western viewers instead see this as suicidal recklessness, incompetence, and Captain Ahab syndrome. However, the trilogy explores both points of view by its conclusion. Haruo's desire for revenge leads to an even bigger threat that is never resolved. But humanity is able to integrate and rebuild with the help of their allies as a result.
YMMV / Godzilla: Planet of the Monsters
