Yet another eighties slasher movie dug out of the vaults; the only conceivable reason this one hasn't escaped the furnace is an early appearance by Kevin Costner. He's playing a significant character and has two major scenes, but strangely he's uncredited in the final title crawl which does include far less important roles as Man Watching Television, Ambulance Attendant #2 and Baby In Crib. (Not only, incidentally, is that end titles sequence the cheapest possible short of asking a passerby to just read them out, but it reveals that the film doesn't even care enough about its victims to give them the dignity of a name, callously billing them as Girl Stabbed In Chest and Girl Killed In Kitchen.)
Hopes aren't high when the Troma logo appears at the start of the meaninglessly titled Shadows Run Black, though this appears to be for distribution rather than actual production (on the other hand, producer Eric Louzil went on to direct two Class Of Nuke 'Em High sequels for Troma). There's a maniac on the loose killing co-eds, a hardass cop with a traumatic backstory, an overprotective racist trying to protect his sister, and several extended scenes of women taking their clothes off and wandering about naked before The Black Angel gets them. Eventually there's a shocking denouement where the murderer is actually revealed as precisely who you thought it was.
It's strictly routine, VHS fodder (it doesn't seem to have been given any upgrades for the DVD era, like decent picture quality), most likely of interest to Costnerphiles than anyone else. As with Man Of Steel and probably nothing else he's ever done, I could have done with more Costner, but it's clear the film's main priority is leering over naked women rather than actually utilising the only person on project with any actual quality. It's all very grubby, it's not very interesting and hardly worth the effort involved in clicking Play.
