Scream and Scream 2—slasher parodies or slasher-parody parodies written by Kevin Williamson—were marked by self-reference. This sequel, written by Ehren Kruger, is slower, more earnest, and not as gory, and its less-cagey tone is reflected in the less-stylized directing by Wes Craven (who also directed the other two) and in the frequent night scenes and scenes set in dim interiors. New characters are introduced and killed off as Neve Campbell faces an ordeal she’d hoped was over, while the movie belabors the idea that it’s the last of a trilogy rather than the third in a series. With Courteney Cox Arquette and David Arquette. 116 min.
