Since we havent met any yet, this cannot be answered. In movies and in Science Fiction in general, some aliens are evil, others are nice, like in E.T. The Extra Terrestrial. Without any data to work with, there is no answer to this question.
If human, Foreigners, if from other worlds- Extra-terrestrials. Aliens is a bad term as it has political overtones ( Illegal Aliens, for example)
because they might be bad, and destroy us for earth so they can live there
At this point, no aliens are coming to eat us, at least known aliens.
First we have to know whether or not they exist.
Nobody knows the answer to this question because nobody knows if aliens actually exist.
if they shot you in the face..their bad
IF they exist it will be either good or bad depending on their attitude and goals.
As much as I would like that no. Too bad right???
`Because we're aliens and we want to rot your brain. Hey, that's how we roll!'
By stopping bad guys, battling powerful aliens, and rescuing people in horrible danger.
Aliens in the Attic, Bad News Bears, Keeping up with the Steins, and Valentine's Day.
cause kid movies are getting worse and worse lol
