First and foremost, I'd just like to say that this movie is sad-VERY sad. Also, if you have a nine-to-five job, this movie may not resonate with you, as you might find it challenging to relate.
This cinematic triumph is rich with underlying metaphors that delve into the concept of true freedom and its consequences. Alongside this, it addresses government corruption, power abuse, and explores our society's perceptions in relation to homosexuality and racism. The main protagonist is in a constant struggle against the forces of governement and society, and the system he faces only becomes more relentless in its resistance against him and his righteous endeavors.
However, ultimately, the laws of nature consistently triumph over human-made laws, giving way to anarchy. Unfortunately, anarchy can be a tough pill to swallow at first. Consequently, the movie implies that the main protagonist and his girlfriend will encounter increasingly challenging choices stemming from their own liberties or the absence thereof. The fluctuations in their freedom throughout the story are left wide open for interpretation - a key element contributing to the movie's excellence.
Randy Newman wrote the main title song for the movie, entitled "Let Me Go," which also serves as the end title song, setting the emotional tone for the tragic theme of this film.
I cannot recommend this movie enough; it's one of the greatest classic movies in my opinion. However, one of the defining dramatic features of this cinematic experience is its seemingly inconclusive nature. It leaves the viewer wanting more answers, and that is the only major complaint I can conjure.
