“THE ROOM” 10 p.m., Friday, Market Street.
You need to know the cues. When a framed photo of a spoon appears onscreen, which, apparently, it frequently does, you're to hurl plastic cutlery at the screen. That's just one of the interactive joys of this cult favorite, supposedly the best terrible movie ever. Last year, Entertainment Weekly found an expert, Ross Morin, assistant professor of film studies at St. Cloud State University in Minnesota, to say just that. “It is one of the most important films of the past decade … the Citizen Kane of bad movies.'' Not that it matters much, but the plot follows a love-triangle involving Johnny, his friend Mark and Johny's fiancee Lisa, who is sleeping with both men. Un-erotic sex scenes figure prominently, too.
