The favourite subject of every horror/sci-fi lover - discussing the creatures that appear in all the universes thrown at us. They have the ability to be awesome and fear-inducing, but if mistreated, they come out as lame plot machines instead. And if the thing that carries your story through the movie is plain boring, what does that tell of the rest of the feature? Take the Xenomorph, for example. That creature is the synonym for the slither of the night; it's absolutely terrifying on a physical and psychological level, making the viewer extremely uncomfortable in their seat. That is the boogeyman done right. If a monster movie doesn't have a 'proper' monster, there is nothing left to carry such a flick into greatness. It either becomes comical to the point it's sad or descends into madness, where nothing makes sense and everything feels wrong. It takes great imagination and even better implementation to make something nonexistent perceived as scary and/or dangerous. In this article, we will take a look at the absolute worst of the many available monster movies. There will be some old and some modern ones, all connected with their genuine lack of scares and the fact that they are laughable rather than frightening.
