zombies, as in the living dead, and impossible to happen. But zombies as in infected, diseased people are VERY likely! With the closeness our world is becoming, an epidemic would spread like wildfire and infect the planet in no time flat. As seen in 28 days later, a disease could spread around the world and kill many people. So can zombies happen? Definitely YES!

Scarecrows, because everyone has seen one, and whether or not its fake, its just creepy because it looks like he's looking at you...very scary

The story is unique, a lot more interesting creatures and characters, and more convincing villains then Star Trek. It seems like every Star Trek episode is the same thing, just involving a new species of alien that is the "bad guy"
