“The Last Exorcist” (*1/2 out of four) was a derivative timewaster about two sisters (Rachele Brook Smith and Terri Ivens) who are haunted by demons from their past and realize they may have to (yawn) have a religious exorcism and they soon become involved with a troubled priest (Danny Trejo in his umpteenth paycheck role). No relation to either “The Last Exorcism” movies but it may as well have since it more-or-less tells the same story and goes through the dreary motions. Let’s all hope this is “the last” exorcism movie and this genre can go back to Hell where it belongs.
