“Insidious: The Last Key” (** out of four) was an enervated horror sequel about the continuing horror adventures of the parapsychologist Dr. Elise Rainier (Lin Shaye) who returns to her own family home to face down further personal hauntings and has to contend with her biggest personal demon yet and (yawn) all hell breaks loose. Fourth (and hopefully final) entry in this popular series is virtually identical to the others and for hardcore fans only or those in a state of depression now that the “Paranormal Activity” series has ended. Some style and scares towards the end but seriously guys- the thrill is gone. Shaye is strong in the lead but hopefully she finds the key for other roles soon.
