“Deinfluencer” (* out of four) was a horrendous horror show that won’t develop any influence of its own about a cheerleader (Caylin Turner) who is kidnapped and imprisoned by a perverse sicko (Simon Phillips) who makes her film and humiliate herself through various social media but she begins to suspect that there may be more to this killer than meets the eye. Film mashes you in unpleasantness and ugliness for over an hour-and-a-half and the cheerleader is so unlikeable you might be rooting for the killer anyway; it’s movies like these that killed the horror genre until “Scream” revitalized it in the mid-90’s. Phillips also co-wrote and created the story.
