Query: Can a book with an orgy be that bad?

I have just finished reading Caryl Churchill's infamous play "Cloud Nine". I found the book to be an amazing tool to present to the reader those social issues which we have so desperately tried to sweep under the bed. The book is actually a play through which her use of a Brechtian style of theater keeps the reader in a sort of shocked confusion and not very comfortable. At first glance you might say it is vulgar and rude, yet a deeper evaluation proves that this play is an effective tool to dredge up what society has sunk to the bottom of the river.
