I love a good zombie film and this ticked two of my personal niche favorites; zombies in World War II. Set during the Japanese invasion of the then Kingdom of Thailand in 1941, the resistance was shortlived lasting only a few hours before the ceasefire was called. This movie adds in the 'zombie' element. While not a new story, as the WW II human experimentation angle ending in a zombie outbreak, is a somewhat well-worn trope (Dead Snow, Outpost, Overlord), Operation Undead does have a unique take on how the undead operate, eating the flesh of the living while trying to keep their humanity but ultimately failing and the world burns around them.

As a fan of paratical zombie effects I was delighted by the ultra gore. Some solid limb ripping, and eviscerations, the plot had be guessing where they were headed right until the end.

As a history and horror nerd I was very much the target audience for this one, and if you like me enjoy a good zombie watch, I recommend.
