In a bunch of interviews, the filmmakers kept getting asked about trying to hide messages about politics and such, and they responded with 'There isn't any hidden meanings in this, we just wanted to make the film really badass.' They even said how they didn't make the fighting very accurate for the period because they wanted to focus more on making the movie look awesome. I'm sure people will find meanings in the movie but I don't think they were intentional.
Think while it's still legal.
