Bad But Not As Horrid as the Reputation
15 January 2011 | by Michael_ElliottSee all my reviews

Navy vs. the Night Monsters, The (1966)

* 1/2 (out of 4)

This now legendary cult movie has the reputation of being one of the worst ever made but I wouldn't go that far. The film has a pretty simple storyline as a Navy base has a plane land where only the pilot is alive and the rest of the crew have mysteriously disappeared. The only strange thing is this acid material that is all over the place. While the doctors try to figure out what's going on, more deaths happen and sure enough it's because of those killer trees brought back from Antarctica. The killer tree genre didn't deliver too many movies and you just need to watch this one to understand why. Again, this is no where near the worst movie ever made but at the same time I will call it one of the most disappointing because it really isn't as bad as what you've heard. I think the biggest problem with the film is that it really doesn't do anything with its silly and stupid plot. Yes, the plot is incredibly dumb but so were the majority of stories that were used for our sci-fi and horror favorites. The filmmakers want us to believe that trees have come to life and can attack people. Fine, do something with it. The first hour of the film pretty much has everyone talking about terrifying these creatures are yet it takes forever to get to see them in action. Once they do go into action we get a few nice laughs because of how silly they look. The low-budget is obvious with the special effects and especially one scene where a man gets his arm pulled off. An even stranger thing is why this movie was made to begin with. Outside it being shot in color the thing really looks and feels like something made ten or fifteen years earlier. When you think of what was going on in the film world by 1966 it's as if the filmmakers of this thing were in a coma and didn't realize how out-of-date their movie was. The performances, as you'd expect, are all rather wooden and this includes cult favorite Mamie Van Doren who plays the head nurse. She's suppose to be playing this brilliant mind but I think you know how that turned out. At least the directors were smart enough to keep her in tight shirts. At 88-minutes this comes off as one of those films where you keep watching and keep yourself entertained hoping that something good eventually happens but in the end there's not enough there to make it worth the effort. THE NAVY VS. THE NIGHT MONSTERS isn't a good movie but sadly it isn't bad enough to be fully entertaining.
