From Wikipedia:
Todd and the Book of Pure Evil is a Canadian comedy/horror television series that follows a group of high school students who confront the effects of a demonic book.
Reruns air in Canada on The Comedy Network (from June 5, 2011) and MuchMusic (clean versions, from September 6, 2011 in HD).
Todd, Curtis, Jenny, and Hannah are students at Crowley High, the only high school in a small town secretly founded by Satanists. After encountering a cursed magical tome with a mind of its own, the Book of Pure Evil, which grants the wishes of those who hold it in dark and sinister ways they didn't intend, they team up in an attempt to track down and destroy the Book, although it has an unfortunate tendency to fly away after its spells are undone. Each episode revolves around a student at Crowley High using the Book to try to make their life better, though this usually results in chaos, mayhem, and bloodshed at the school. Todd and his gang then fight against whatever the Book has done, and try to keep Crowley High from being totally destroyed. Supposedly friendly school guidance counsellor Atticus Murphy helps them in their quest to destroy the Book, though secretly he is a member of the cabal of Satanists who run the town from behind the scenes, and has been tasked with returning the Book of Pure Evil to their leader.
From the Winnipeg Sun:
'Book of Pure Evil' is pure fun.
Todd & the Book of Pure Evil "mainly has the feel of Buffy the Vampire Slayer with potty-mouth."
