TORONTO (CP) - The upcoming release of a Canadian horror flick that features a serial killer on a Christmas rampage has raised the ire of religious advocates south of the border but barely raised an eyebrow at home.

Canadian religious advocates dismiss "Black Christmas" as a typical slasher film that shouldn't be given the free publicity it's enjoying in the United States.

Groups like the Ohio-based Operation Just Say Merry Christmas say the trailer's use of holiday images to promote the Dec. 25 release is an insult to Christians.
