I don’t know if it’s interesting, but it is an observation, although most likely one that many have made already.
Aliens in movies and television. They’re often very much the same, that is; a lot more technologically advanced than we are. They have huge spaceships, gadgets, they are more cognizant in their senses, and of those beings inferior to them, in all known means, and beyond.
They’re always naked. Aliens never wear clothes. They never speak, but instead communicate through sounds which we would register as grunts, screeching and the like. They all look the same. Unlike human beings, an alien race never seems to have physical variation to represent them.
Many times, they are also very agile, fast and strong.
I don’t really get why super smart and evolved aliens with uber ass technology pretty much act like monsters, or at least have the physical qualities of them. This isn’t something I mind or have anything against; but it is an observation which I’ve made.
Of course there are exceptions. Races in Star Trek are much closer to humans in many ways. Xenomorphs have no known technology they use or create, and act like ants, from what I may gather. I’m sure there are plenty of other different types of aliens, I’m not a big sifi buff at all. But the super intelligent naked alien we can’t directly communicate with seems to be a returning concept, again and again. This is besides the skinny gray alien with a big head and eyes, which seems to be a stereotypical portrayal of the popular alien, rather than something that’s actually used a lot in entertainment. Then again X-Files may beg to differ. Never really watched those.
