Horrifying in what way? In the sense of being nearly impossible to navigate taking into account their gravitational effects? If these black holes are just as dense as in the galaxy, wouldn't that make navigating the galaxy just as difficult? The distances are longer, but that just means corrective burns have a stronger effect on the future trajectory.
