“Pathology,” starring Alyssa Milano and Milo Ventimiglia (he was played Rocky’s son in )- is about a group of medical students who hatch a scheme to see who can commit the perfect crime — one that even a fellow pathologist couldn’t unravel. Will it be DOA? Or will “Pathology” be the first big hit for MGM? We’d venture to say the low budget movie “Pathology,” if marketed properly, could make its money back. But with the recent releases and bombings of and every other slasher/horror film last year, we are a bit skeptical.
