It shows a true lack of imagination. They are aliens EXACTLY like Americans. How lame is that? They even have the same body type, this is so dumb. Aliens would be so drastically different from us in every way, including culture and how they build their homes, how they live, how they act... their language. This is crap, I demand better.
"Terra" was a much better movie with the same plot. I noticed in the trailers for Spring 2010 that another movie has this same plot. A child could come up with something better.
