You wanna make a serious minded monster movie? Well, the result is going to be taken as symbolism, [[EveryoneIsJesusInPurgatory regardless of what you intended]].

Here, then, are some of the standard Monsters from OurMonstersAreDifferent, with notable examples of said symbolism as interpreted.

!! Vampires
* Anything to do with parasitism or disease, including:
** AristocratsAreEvil
*** {{Dracula}}
* WhoWantsToLiveForever
** Too many VampireDetectiveSeries to mention
* VampiresAreSexGods
* Bloodthirst as a metaphor for drug addiction
* The need to kill to survive

!! Werewolves
* [[SuperpoweredEvilSide The Beast Within]]
** ''Film/TheWolfman1941''
** Just about every other werewolf using the whole amnesia shtick.
** [[HulkingOut Anger]] and Rage.
** SplitPersonality
* Metaphor for [=STDs=]
** ''Literature/HarryPotter'' (according to {{Word of God}}, although the evil werewolf Fenrir Greyback gives off hints of pedophilia as well).
* Metaphor for menstruation
** Used by Creator/AlanMoore in ''ComicBook/SwampThing'' and Creator/JossWhedon in ''Series/BuffyTheVampireSlayer'', as well as a direct connection in ''Film/GingerSnaps''.

!! Zombies (of the ZombieApocalypse variety)
* HumansAreBastards
** [[InYourNatureToDestroyYourselves Mindless, ravenous consumption]]
* Survival of the Fittest
* Faceless conformity and loss of identity
* Epidemics, especially when zombieism is TheVirus.

!! Zombies (of the HollywoodVoodoo variety)
* Slavery
* Again, faceless conformity and loss of identity
* Fear of being BuriedAlive

!! [[InvasionOfTheBodySnatchers The Body Snatchers]] and similar
* Conformity and infiltration are the watchwords here.
* Frequently associated with a RedScare

!! [[{{Kaiju}} Giant Monsters]]
* Disasters. Either man made (Hedorah, giant robots, mutants) or natural (Rodan), a sort of divine retribution tied to shinto beliefs can also be read into it (Mothra).
** Franchise/{{Godzilla}} has basically been all of the above at some point. He started out as a metaphor for the devastation of the atomic bombs dropped on Hiroshima and Nagasaki. ''Film/GodzillaMothraKingGhidorahGiantMonstersAllOutAttack'' has him being the collective manifestation of the souls of those who lost their lives during Japan's Pacific campaign in UsefulNotes/WorldWarII. ''Film/{{Godzilla 2014}}'' gives him a GaiasVengeance characterization on top of being a radioactive mutation.
* Abuse of military power. Almost always military might will fail miserably and just waste everyone's time, and often it's the fault of the military that the Kaiju are there in the first place.
* The threat of [[AtomicHate Nuclear Weapons]] and other [[WeaponOfMassDestruction weapons of mass destruction]]. Nuclear Fallout.

!! Alien Invaders
* Human imperialism and war.
** The original ''Literature/{{The War Of The Worlds}}'' novel was largely meant as a critique of the British Empire and imperialism in general.
* Human reaction to disaster, similar to zombie films in that the people are more of a problem than the invaders. Also an element of all War Of The Worlds adaptations.

!! Aliens in general
* Foreignness and [[HumansThroughAlienEyes other cultures]].
* [[FiveRaces High Men]] and [[ClarkesThirdLaw Gods]] - great power, interfering with humanity according to mysterious rules.
* AmbiguousDisorder or 'oddness'

!! [[FrankensteinsMonster Mad Scientist-made Monsters]]
* ScienceIsBad / MyGodWhatHaveIDone
* TurnedAgainstTheirMasters
* [[GoneHorriblyWrong Unforeseen Consequences of Human Industry/Technology]]

!! [[OurCryptidsAreMoreMysterious Cryptids]]
* Human interaction with nature and RomanticismVsEnlightenment-- cryptids are usually described as living in areas of untouched wilderness and hunted by humans with fancy technological gizmos. Heroes often have to help them escape and be left alone in the wild, without human interference.
** ''Tintin in Tibet'' ends with the hero saying he hopes humans never catch the Yeti, because they'd only put it in a zoo.

!! Robots
* Slavery - the word 'robot' is derived from the Czech for 'slave' - or workers in general, which also makes them useful for talking about Communism. 'Robot revolution' stories - whether the story was on the revolution's side or not - were especially common in the early half of the 20th century, but fell out of fashion once revolutions stopped seeming likely and the UsefulNotes/ColdWar began. RedScare stories featuring robots in this era will often suggest they are disguised perfectly as humans, hiding amongst humans and spreading evil robot ideas. Even fairly apolitical robot stories tend to depict them as 'lowly' characters compared to the humans due to their life of drudgery, which sometimes allows them to be {{Servile Snarker}}s or even [[TheButlerDidIt so beneath notice as to be able to commit murder...]]
* Dependence on technology and possessions - the idea that a possession, in some way, owns its owner. Or, less frighteningly, the idea that a possession might have a 'soul'.
* The meaning of human consciousness, humanity or the soul. In stories like this, robots are often depicted as being essentially 'human' and with consciousness but condemned to be treated as a 'thing' due to their artificial minds. They may be fighting to gain the rights of being recognised as human, which can be read as a metaphor for civil rights movements.
* RomanticismVersusEnlightenment, when a highly intelligent but emotionless robot is pitted against less intelligent but loving human beings.
* The failings of rules and law compared to intuitive thinking - in stories like this, robots will be incapable of disobeying seemingly harmless rules, resulting in awful consequences in messy real world situations.
* Destiny - a robot is usually made for a specific purpose, with abilities to allow it to do its job, and often with the inability to choose ''not'' to fulfil that purpose.
* Anxiety about death - robots can't be killed due to not really being alive and tend to invoke the UncannyValley (the lowest point on which is an animated corpse).
