This is definitely not a film with a lot of sex or even a lot of nudity in it. Grey is topless in a handful of scenes, but that is really it. It is more about the overall life of a call girl. There was much more sex in the series adaptation that aired on Starz. The movie most definitely has an indie film feel, and it is not fast-paced at all. The character of Christine was written to be very reserved with a lot of emotional barriers, so Grey really was not able to show the personality that she does in her YouTube videos.
For those who get the Blu-Ray, there are two cuts of the movie, the theatrical version and the unrated cut (which does not really add much at all to the movie, and unlike what some may think does not have any salacious sex in it). There is a commentary track on the movie with Grey and Soderbergh, a very short making-of featurette, and a few trailers for other movies.
Overall, the movie is good, but not great. It can definitely be a bit slow at times, but it does have a lot of great visuals of NY, which do look really good in HD. Grey was very young (just 21) when the movie was made, and she definitely gives off the vibe of trying to act like she's more in control of her life than she actually is. Whether this was true for her real life or just as the character she was portraying was hard to tell, but either way, it worked. It is not a movie that is going to appeal to everybody. But if you are a fan of indie movies and don't mind a slower, documentary-like style, then this is worth checking out.
