movie review SCREAM 7 Running time: 114 minutes. Rated R (strong bloody violence, gore, and language.) In theaters. In the middle of the stupefyingly bad seventh “Scream” movie, Sidney Prescott asks her daughter’s boyfriend, “Do you know anything about AI?” Oh, I screamed all right. Noooo! Anything but another slapdash horror film with a lazy plot that hinges on artificial intelligence! But that’s all “Scream 7” is — the same old regurgitated slasher mush Hamburger Helper’d with a dash of AI.
