‘Zombies 3’ makes it hard to get fired up for a sequel that feels dead on arrival

Of all Disney’s teen-musical franchises (see “High School Musical” and “Descendants”), “Zombies” overcame its strained cuddly-zombie premise to become the most unexpectedly pleasing, augmenting its themes of bigotry and acceptance with best-in-class songs. Given that, there’s little pleasure in reporting that “Zombies 3” is creatively dead on arrival, reviving the concept at least once too often.
