The Grim Curriculum is a dark-topic conversation show with a distinctly casual spine. Charlotte and Dina often take their time getting to the formal subject, opening with life updates, gaming plans, weather moods, show anniversaries, or the emotional hangover from a previous case. That looseness is part of the texture. It makes the eventual pivot into murder, disaster, strange death, or conspiracy feel less like a lecture and more like being at a table where someone has done the reading. Recent episodes show the range clearly. Lizzie Halliday brings violence, arson, disputed sanity, and the kind of escalating case detail that invites horrified reactions. Allan Legere brings Canadian serial-crime history, news memory, and the shock of realizing how large a case can feel while still being unfamiliar to some listeners. The 1917 Halifax Explosion gives the show room for historical catastrophe rather than only individual criminality. Extra Credit episodes are looser and faster, moving through true-crime updates, conspiracy-adjacent stories, questionable decisions, odd deaths, and grim news items with a lighter structure. The show can be funny, but it is not careless about harm. Victims, children, abuse, and fatal violence are treated as serious material, even when the hosts make room for disbelief or a sharp aside. Its best mode is conversational momentum: one voice carries the researched line, while the other reacts, clarifies, or catches the human absurdity in a terrible fact. The show is especially suited to listeners who like true crime with personality left in. It does not hide the banter. It uses it as a way into difficult material.
