“Campton Manor” (*1/2 out of four) was a boring horror thriller about a faded author (Jeremy London) who investigates a ghost story that leads him to the mansion of a wealthy businessman (Kenneth Welsh) but nothing is what it appears and he starts mentally unraveling. Yet another film that really makes you wonder what horror filmmakers would have done had “The Shining” not been made because it’s still being ripped off decades later. Of note solely for being the final film for Canadian character actor Welsh.
