They are terrible actors but I think they were handled well. Because the characters were written for them, they really just had to be themselves.
I think their prominence in the movie is what resulted in such a bad score. Even without the personal controversies, they are polarizing artists. Few people have a neutral reaction to their stuff. At the time I was pretty into their music, so seeing them in the movie was fun for me.
I have many friends with nipple piercings.
