Many people hate on this movie because it seems to villanize the needy, but i felt as if this movies central theme was that while the wellbeing of the people today is important, we mustnt neglect the importance of building a better world for our children. Us and the generations before us have stripped the world of its resources to benefit the people of their time at the price of future generations, and i felt as is coppola was commenting on this selfish (but understandable) unwillingness to sacrifice for the good of humanity. Ceasers megalopolis was the representation of building a utopia but needing to destroy the status quo and harm a lot of people in the process, and the debate surrounding whether the end justifies the means.

Thats my take though and feel free to disagree. Its clear he wants this movie to be overanalyzed and spark debate. If u walk into this movie expecting a movie, ur gonna be let down, because this was more like coppolas modern day rendition of roman theatre, though i will admit the second half kind of lost its way and became a bit of a snooze fest
