Should be better known - and higher rated!
Cult Canadian slasher that made the infamous UK 'video nasty' list at the time. Lee Grant's crusading TV journalist becomes the target of Michael Ironside's complete psycho. After being attacked by Ironside in her home, Grant is admitted to hospital with serious injuries. Ironside follows her there to finish the job (coldly dispatching anyone who gets in his way). When Grant starts to 'rant' that she believes her attacker is in the hospital, Linda Purl's nurse is the sole person who believes her - only to then become a target herself. William Shatner - as Grant's initially sceptical boss - comes to realise that Grant wasn't as deluded/paranoid as he first thought.
Shatner is as entertaining as always (still wearing his TJ Hooker hairpiece), Grant and Purl are good (both were major crushes for me in my youth) - but the movie 100% belongs to Michael Ironside, who gives a top class performance as the killer; single-minded and calculating throughout, he's chilling, relentless, and totally believable. I don't know if Halloween II, which came out just seven months before, had any influence on this (it seems a bit tight), but they would make a great double feature - and Visiting Hours would easily hold its own. 7/10
