The film in terms of form was successful in excitement and suspense but in terms of content was bad

Rating: 3/10 (20 October 2017)

The film in terms of form was successful in excitement and suspense but in terms of content was bad and apologized for .. I searched for moral value or a message to take advantage of .... I only found a bad feeling (racist movie) .. I work in acting and know that every work of art It must be a moral value and a message to the viewer (sometimes there are only entertainment films for example horror movies) but in this movie there is only excitement and suspense with a bad feeling when I watch ..... Jordan Peele was a great director but the film writer needs more maturity to be the end of the film away from racism (for example could be a friend Chris white man) .... Please answer my question: What is the value or message through the film ?????
I apologize for dictation. Please accept my remarks
Thank you
