What's unrealistic is the idea that occupation would occur in the first place

What's unrealistic is the idea that occupation would occur in the first place. They'd just destroy us, and although it wouldn't be a fun ride, it would make for an interesting few hours of television. Instead, we have to watch good, old-fashioned earthling spunkiness take care of a vastly superior force.One of the primary ways we stop an replica Tag Heuer Unisex Watch alien invasion in movies and television is by finding the alien's one big weakness. There's some hinting at that in Falling Skies. “These things can be hit,” a gruff man with a gun says, “And they can be hit hard.” They have a vulnerability. In Skyline — spoiler alert — it was true love.

The problem with every such One Big Weakness is the audience starts picking apart why the key was that one weakness and no other.In Signs it was water, but did it have to be fresh water? Wasn't it raining anywhere? Snow? And what about the water in the human body? Even though most of the body's water is suspended in cells, there's a lot of moisture left over. What happened to the aliens whose victims cried like a baby and replica Tag Heuer WW2118.FC6216 Watch wet themselves - as I most certainly would if I were being attacked by a clawed chameleon alien. Did those aliens die?And what about the other people in Skyline? Did they not love anyone enough to take over their brain-eating alien hosts? The One Big Weakness is a tiny crack that is meant to end the movie happily but instead bursts it to pieces.

Sure, we're all happy to suspend our disbelief - with a crane if we have to - because laser fights and big alien ships are cool and we like to watch them. But any alien force so advanced that it can cross vast reaches of outer space would make short replica Tag Heuer WW2117.FC6216 Watch work of us. Remember, we're not just talking about technological advancement here. Space travel comes with a whole host of chemical, physical and biological challenges that have to be met.
