Monster movies have been popular throughout the entire history of cinema, as creatures, beasts and ghouls have filled the screen and terrorized people, cities, and even the world. We think we've narrowed it down to 10 different classes of monsters who do the terrorizing -- the 10 types of outbreaks, if you will. If you won't... well, reading this list is going to be awkward for everybody.
People like werewolves because its like mixing man's best friend with man. werewolves are their own best friend, and that's pretty convenient. Except of course your own best friend tends not to want to savagely tear people apart (hopefully). It's okay though, because it only happens every once in a while, when the moon is full. You will see werewolf outbreaks in Silver Bullet and American Werewolf in London, or Teen Wolf, though the latter isn't really frightening as it is a role-model for life. Although Teen Wolf 2 is also strictly horror.
9) Giant Insects
We spend a huge amount of time making sure that little crawling creatures aren't in our home, waking us up by crawling into our nose. So it's pretty natural for us to use insects as an inspiration for monstrosities. Take for example Them! from 1954 -- it consists of giant ants THAT WILL DESTROY AMERICA, enlarged by (of course) atomic radiation. There's also the notable Kingdom of the Spiders, featuring William Shatner, The Wasp Woman (not featuring William Shatner) and Mimic (also sadly lacking William Shatner). A case could be made for Starship Troopers as an insect movie as well, though they are technically extremely bug-like aliens. There's also the case of The Fly which asserts one of humanity's worst fears: turning into Jeff Goldblum.
8) Little Creatures
There's always some sort of little mischievous murderous creature that's ready to wreak havok. From Gremlins, to Critters, to Troll 2s, we sure like the little bastards to show up and kill us. Usually innocently at first and small in number, then grow to a horrible multitude that screws things up royally. The solution always seems to get them together in one little spot and then someone blows them up with a huge explosion. Maybe humanity just really like to blow up midgets. Perhaps it's best not to examine this too much further.
Giant beasts are always good for a show, mostly because they are so giant and they look really impressive on the big screen. Or they don't look impressive at all, and it's really funny to watch them with a large group of people. Godzilla is of course the gold standard when it comes to giant monsters, along with Godzilla vs. Mothra, and Godzilla 1985 oh, and something not Godzilla, like the Cloverfield... thing, and I guess King Kong. Oh and Megashark vs. Giant Octopus. We just like the idea that somehow nature will get the upper hand on us by simply being way way bigger than us.
Oh our metal machines, can you ever stop killing us? That Man's own robots will be smart and decide "hey screw this noise" is a premise that has been going on for a long long time. From Metropolis to the Terminator movies to The Matrix, they show up to kill all us meatbags and replace us with a smooth, iPhone-like society. Who doesn't love a good metal monster pulling apart humans like fresh bread? Nobody, that's who.
