I don't get it, people keep saying 'Uh, if it takes place anywhere else besides the hospital, power plant and sewers, it gonna suck!'. The Aliens are always looking to expand their nests, they're not just going to keep to one place and that's it. They're going to expand where ever they can. Whether it be schools, churchs, strip clubs, hunting stores, anywhere. I would think that would make it more realistic than them just saying 'Okay, we made our nest here, and now we're going to stay here', whereas the movies show, they're always looking to expand their nests and look for more hosts. They're like bees, only big, drooling, acid-bleeding, lion-like bees.
