It’s possible its themes might connect more strongly now, given recent events, but honestly, I didn't find it particularly exciting or original. The story involves a deadly virus being unintentionally unleashed in a small Pennsylvania town, and the military is tasked with preventing its spread across the nation as it causes a slow, yet permanent, descent into madness. "Col. Peckem" (played by Lloyd Hollar) carries the weight of this difficult mission, dealing with an impatient local mayor, communication breakdowns, and a community that’s rapidly spiraling toward chaos and danger. Things are further complicated when pregnant nurse "Judy" (Lane Carroll), along with her firefighter husband "David" (Will MacMillan), attempt to flee the quarantine area, forcing Peckem to pursue them. Then there's "Dr. Watts" (Richard France), who’s desperately searching for a cure by taking blood samples from practically anyone and everything he can reach with a needle. Essentially, this is a typical contagion horror film, but it feels very ordinary in its production quality. The performances are weak, the writing isn’t much better, and the ending is about as unbelievable as you could get. If viewed as something silly, it might elicit a few laughs as the townspeople gain increasingly zombie-like abilities and strength, but it's just a pale imitation of more engaging films in the style of Hammer Productions, lacking any real sense of danger. It does reinforce the familiar idea that the U.S. military is skilled at creating issues but struggles to resolve them, though I doubt that’s what George A. Romero intended with this rather lackluster project. I watched it on a large screen recently and managed to finish it, but I won't be revisiting it.
