In A Monstrous Corpse (AKA Strange Dead Bodies), an experimental ultrasonic machine designed to kill harmful insects has an unfortunate side effect: it brings the dead back to life as bloodthirsty zombies. A young woman, Yu Si-ji, and recent acquaintance Kan Myeong struggle to convince the police about what is happening.
If this sounds familiar, it's probably because it is the exact same plot as '70s Spanish/Italian zombie classic The Living Dead at the Manchester Morgue by director Jorge Grau.
This unofficial Korean remake fails to deliver the atmosphere and the gore that made Grau's film such fun (that film's blood and guts earning it a place on the UK Video Nasty list). Also serving to make this Asian copycat far less impressive than the original are the pathetic zombies, which are incredibly slow and not very scary (the cheap make-up consisting of silver face paint), and the unremarkable cast (Grau's film starred Cristina Galbó, Ray Lovelock and Arthur Kennedy -- tough to beat that line up!).
A Monstrous Corpse may be of some interest to avid zombie movie fans, just so that they can compare and contrast, but don't expect too much... you'll only be disappointed.
2.5/10, rounded up to 3 for several unintentionally hilarious scenes: Detective Jee's reaction upon seeing the zombies (blinking exaggeratedly several times in comical fashion), the people running around the hospital in panic, and the way that Yu Su-ji loses the ability to stand up when being pursued by a zombie.
