“Black Friday” (**1/2 out of four) was an engagingly silly and over-the-top black comedy about a group of toy-store employees (Devon Sawa, Ivana Baquero, Michael Jai White, and others) who must unite on the day after Thanksgiving when a parasite infects various shoppers and turns them into otherworldy zombies. Cheeky visual style and sardonic and cynical sense of humor is in the vein of “The Evil Dead” series (with Bruce Campbell cast as the toy-store manager); a little of this goes a long way but at least it never stops moving and trying for you to have a good time. Filmed in a former Babies ‘R’ Us in Massachusetts!
