What makes a movie radical is only partly its content....what it has to teach. But the other part has to do with the manner in which it allows the audience to be reborn as an active agent, to be aware of powers it did not know it had, of an understanding it did not know it had, of roles it did not know were possible.
So, Burn had radical content, but it was mostly discursive. That's not evil, it's just limited.
