“The 6th Friend” (*1/2 out of four) was a by-the-numbers timewaster about six college friends (Dominque Swain, Jamie Bernadette, Chantelle Albers, and others) who reunite but the party is crashed by an uninvited guest which leads to a night of revelations and bloodshed. Anyone who has seen a few horror movies in their lifetime will have no difficulties figuring out who will survive and who won’t. For the same story told with much more styles and scares, watch “Sorority Row” or “Black Christmas” (or their remakes) instead.
