The Zombies have finally taken over the world, as we discover at the very beginning, when the last surviving humans venture out in a helicopter to search for any survivors in the big city, but only discover they are over run with not only human Zombies but animal Zombies too.

The search party then return back to hide out, were they are staying, and it is here we find out they are being dictated to by a group of soldiers who are cracking up more and more as each day goes by. Their leader wants results he wants to know if there is anyway they can defeat the Zombies, which are surrounding the underground camp they are staying in, as well as the rest of the planet.

There is also a mad scientist in the camp who resembles more of a Dr. Frankenstein, and therefore receives this nickname, due to the bizarre experiments he conducts, but he eventually goes too far as he tries to train one of the Zombies to learn its human instincts again, he feeds it on the remains of their old leader who died, and was thought to have been buried by the other soldiers. When they find out this increases the tension between the scientists and the soldiers, who finally crack and start shooting up the scientists.

The scientists have to fight back and fast too as there will be know rational humans left if they all get killed. So one of them decides to open the gates of the army complex and let the Zombies in. Whets left is a last ditched effort by the remaining scientists to survive against both Zombies and soldiers, and get to the Helicopter and try to reach some tropical paradise.... The result is the darkest day of horror the world as known......

Yep I'm afraid so, it was one of the darkest days in horror when I first viewed this film, as I was disappointed with it to say the least, after the excellent Dawn of the Dead this the final installment of Romero's Zombie trilogy was quite a let down. On viewing it again years later though I changed my opinion slightly and must say that overall it's not that bad, not a classic like the first two but still watchable. I once read an interview with George A. Romero and he actually stated that he was disappointed with the way Day of the Dead turned out.
