I watched "Battle: Los Angeles" recently, a movie about aliens invading the Earth. It wasn't terrible, and it wasn't great. It was watchable, and worked sufficiently well in lowering our supply of popcorn at Chez BA. But like every alien invasion movie I see, there's one small, really eensy-weensy problem: the reason they give for the invasion itself was dumb. [SPOILER] They came to steal our water? And use it for fuel? Say WHA?

Ignoring the silly idea of using water for fuel -- that's got physics exactly backwards, since you get energy out of combining oxygen and hydrogen to make water, and it takes energy to crack them apart -- there's an even bigger problem... ... which I won't tell you here, because I go into all sorts of detail in my latest Blastr article, 6 Reasons Why Aliens Would NEVER Invade Earth. Mind you, I'm not talking about aliens just coming here to shoot the breeze, but aliens coming here to shoot us. It's hard to think of a good reason they'd do so, and certainly the reasons given in pretty much every movie don't make sense. And I have a real problem with just how bad aliens are at taking over. Wiping us out should be pretty easy; heck, I wrote a whole other Blastr article about that, too. So head on over there and give it a read. Agree, disagree? Leave a comment there, too. But if you disagree, be nice: I'm way better at wiping out life on Earth than any Hollywood alien could hope to be.
