Review of 50 Shades of Grey: The film

This week has been performed for the first time in the cinemas the movie "50 Shades of Grey", one of the most anticipated movies of this year.
The book has sold many units although personally I think is a very special story, or even a bit unreal, and denigrating for the women (I haven't read the book, but from what I have seen I know more or less the story). I have also seen some dialogues between the characters, and personally I found these stupids.
Maybe I don't like this movie because I'm a guy, but also has been criticized by many women, although it has been a great success.
