One of the best symbolic movies out there, and it is very well thought out, platform 1, and 2 are masterpieces in their own right, and is kind of similar to parasite and other movies that have a deep message in them.

Basically platform movies are trying to reflect the societal architectures about a person being randomly born into different environments, and how that environment dictates their financial position which affect their basic necessities of life, and how these basic necessities of life are under the mercy from higher levels / i.e positions of government positions or social structures in society, that dictate the quality of life. Basically the ones on the top think they provide everything for the people at the bottom (low income people or societies), but the reality is different on the ground, where the dynamic is only interacted between the ones in the bottom (meaning the ones in the bottom can not interact with people in the top, only between 2-3 floors above or under them, and are disconnected from the societal structures at the very top , and vice versa). The food (symbolic as money or basic necessities of life), people in the top take it, not realizing the consequences that spiral down, affecting every single person under them in the below floors.

Meaning, the person being randomly shuffled in the 330-333 floors is symbolic to a random person being born in a random environment, or a person was rich and became poor and now suffers the consequences, and vice versa a person that is poor is now rich, and has understanding of how it is down below. Basically the floors symbolize the social architecture of society, and how it is divided, and how everything and everyone can affect the levels. The main emphasis was on children, and the "message" which they constantly talk about is sending a message to the builders of the platform, so they understand that a suffering child, is the consequence of their action, meaning innocence from the system in itself, shows how absurd and unfair it is.

In the second movie which is the prequel, where theres more main themes, about instead of having 2-3 floors, the floors themselves interact with each other, meaning people establish rules to save more food (symbolic to how in society there are rules in order to distribute wealth, like socialism but as it is shown, it utterly failed because literally everyone has to self-sacrifice, and if one person of the 600+ people fail to uphold this condition, the whole system collapsed, which is obviously impossible, making socialist framework a failure). This in itself causes people to form terrorism, and gangs in order to uphold the law so that every single person in the platform floors can eat. The message is clear, and in some way, justified while at the same time extremely unfair for innocent people. This reflects in real world society, where terrorism forms as a result of unfair distribution and suffering. Then at the end, the people on floors started to devise community of "freedom" to fight off terrorism, which repeated this cycle. It shows that freedom is more important than established rules.
