While it really isn't a show for an 11 y/o, other than what you've already mentioned there is a fair amount of swearing, as well as some pot smoking. There really isn't a lot of sex. Spring Awakening was more lewd. It's really just very adult subject matter. The show will probably bore her, but then again, I don't know her personally.
"If this is going to be a Christian nation that doesn't help the poor, either we have to pretend that Jesus was just as selfish as we are, or we've got to acknowledge that He commanded us to love the poor and serve the needy without condition and then admit that we just don't want to do it." -Stephen Colbert
