The focus on this seems to be more on the film industry, though it does present a good overview of the issues of debate and areas of interest. Tarrant has obviously read the material, and she notes ares where the data doesn't provide a clear case either way. She also uses more than one research study, including those outside of the US. At times, I found the format a little off - for instance shouldn't all the issues surrounding Deep Throat be brought up when it is first mentioned - but it is a very good book. ( )
