We’ve always had a thing for big-screen aliens. From the small, creepy crawlers to huge otherworldly beings, when Hollywood throws us a flick with aliens, we usually run (not walk) to the movie theater. And if those aliens are popular, then get ready for sequels … lots of them. The alien hitting theaters this weekend is used to sequels (it’s currently on its fifth film), but according to critics this might be its best installment yet.

2. Giant Bugs (Starship Troopers) – While, technically, these creatures aren’t aliens (because we humans fight them on their home planet, not ours), they still need to be included because, well, they’re horrifying as all hell. Imagine giant speedy spider-things that kill you by either stomping, impaling or eating you. Yum.
3. The Blob (The Blob) – Yuck, what’s worse than a giant, gooey blob that devours everything in its path as it grows larger and larger? Grosser than my stomach feels after scarfing down a fast-food meal? I’d say … plus, who wants to be eaten by a giant blob? Kind of an embarrassing way to go, eh?
4. Predator (Predator) – Perhaps the most “together” of all our creepy aliens, Mr. Predator makes the list because a) he’s awesome, and b) his blood glows in the dark. While he’s more of a weapon-wielder, Predator is also fond of gutting his victims and then hanging them from trees. If you don’t think that’s a revolting enough trait, then you make an appointment with a therapist right away.
5. The Thing (The Thing) – Next to Alien, The Thing from The Thing is probably the second creepiest alien of all time. Not only can it adapt to look like anyone, but it can also turn into a giant spider or a nasty-looking batch of tooth-filled flesh. Can anyone recommend a good dentist who doesn’t mind losing his (or her) life in some horrific way?
