More sexual content than the review suggests
Obviously reviewers can't be expected to watch every single episode of a show, but occasionally this results in an under-representation of the content. There is a lot more sexual content in the show than indicated in the review, including nudity and sex scenes, as well as sexual language. As is the case with most shows made for Showtime, this program is intended for adults and the rating is based upon that. Quality-wise is in the eye of the beholder; I saw it as being essentially a variant on the Entourage concept, myself, only with an actor playing a fictional version of himself in the central role.
