I think one of my theatre heroes answered this question really well on her blog:
That being said - there is no representation of violence. There is a lot of talk (including graphic descriptions) of violence. There is no nudity. There is a little bit of sex and the play "acknowledges and discusses sex" as they might say on public radio. There are a lot of "bad" words. There is a fair amount of consumption of alcoholic beverages. But is it right for your child? I dunno. That's up to you. If you have a specific question let us know we'll do our best to answer.
