OK years before Halloween, the UK was the setting for a haunted house film run by a cast of "teenagers". Having said that I actually liked most of it. On the plus side is the late sixties setting, especially the fashions and decor, some of the acting, O'Sullivan, Sewell and Gina Warwick as Sylvia put in decent performance. On the minus side is Avalon, who can't act much, would've been far better if his part had been played by someone like Cliff Richard. That would've been quite subversive. All in all a nice slice of late sixties 60's kitsche.
