Aside from the profanity jokes and parody villains, I really think that the film also had a good story and demonizes censorship extremely well. The story's main idea really shows how censorship can be racist, murderous and sometimes even tyrannical.
Some scenes are also shown to be dark yet beautiful.
One good thing about this movie is the jokes and heavy profanity as it does crack you up but, to me, its also the good storytelling and themes. and this is hands down, my most favorite musical of all time.
