I still love a quote I had read from one reviewer.
Apparently, the aliens were too busy perfecting space travel and going fast than the speed of light to spend any time on making sure they've got Norton Antivirus running on their computers.
If they ran Norton Anti Virus on their space ships they would have never made it to earth. They would be stuck at 100mph barely getting by pluto's gravitational pull.
OH yeah that Bill Pullman presidential speech is why no one but the US likes the US. Lame sauce.
