Blood Oath (2006) is one of the new crop of indie slasher flicks, so you know you’re going to get a thigh-deep heap of “homages” to movies that were forgettable when they originally showed at the drive-in, and characters who are are periodically lobotomized so that they’ll behave as only characters in slasher flicks behave.  It’s hard to measure the success of a movie which aims so low.
