The Daikaiju genre (a term used for the genre focusing on giant monsters) is a genre that on the surface seems nothing more than mindless action involving giant monsters but that couldn’t be farther from the truth. This genre focuses on giant monsters destroying building but underneath the rubble is an allegory for destructive nature of mankind itself
At the end of the second world war the Americans dropped an atomic bomb in the Japanese cities of Nagasaki and Hiroshima causing mass death and colossal damage, the Japanese responded as all good people do by making a film out of it. 
The 1954 film gojira desplayed the force of its titular monster but at the same time it also represents the atomic bomb. In the movie gojira is brought into existance but the atomic bomb tests that acuured in the early 50’s and it is evident that both the wepon and the monster has similar effects. The people of japan are ravaged by gojira and direct parrales are drawn to what happed almost a decade prior. Over all gojira himself is an embodiment of the atomic bomb and is ment to represent the death brought by the bomb as both the monsters attacks and the bomb were caused by the invention of nuclear wepons, something this film makes clear should never have happened. Simmilarly most films of this genre that came from the 1950’s and 60’s also share the theme of the monster stemming from humanitys own cause such as the 1956 film rodan focusing on a monster awoken by mining or the 1962 film mothra being about a large moth attacking because of the vialation of its natural habitat
Just as the threats to humanity have changed in the real world, these movies have changed to reflect the modern age, the gamera trilogy from the 90s focuses on humanity discovering that there was another civilisation before them who met its end by its own doing reflecting on how some theorise that man will meet its end by its own hand rather than by some other force.
Even the modern era films such as 2016’s shin Godzilla and the current series of films by legendary pictures have shifted focus to the problem coming from humanities treatment of the planet such as pollution and nonrenewable energy whereas the monster who are presented as natural animals live in a better and more sustainable way.
Now I’m going to talk about the kind of shots that are common in this genre.
Low angle shots are used when showing the monsters in order to make them come across as more powerful and seem larger than life, there are also a lot of point of view shots taken from the perspective of the people on the ground, this simple technique helps to make the creatures come across as grand not only in size but also power
The creatures in these movies are less monsters and more metaphors, metaphors for humanities flaws, nuclear weapons, the destruction of the environment and the force of nature and while some see them as mindless action under the skin they are so much more
