My, we've seen this one before. A handful of teens, delegates of every clique in the high school melting pot, find a prime piece of real estate to party and get themselves dead. Oversaturated by "Scream" and its offspring within the last decade, the concept has all the appeal at this point of a sweaty, naked cheerleader abandoned in the backseat of a car after a football squad love fest. Spent. Used up. Unattractive. But like a recent spate of slasher fare-with-substance - "Behind the Mask: The Rise of Leslie Vernon" and "Hatchet" - "All the Boys Love Mandy Lane" is a healthy alternative to the sub-genre's monotony.
