10. Independence Day: The computer virus - This movie has so many unanswered questions that one is forced to conclude that most, if not all, really are just plot holes after all. But then there’s the computer virus that Jeff Goldblum uploads into the alien mothership, that is ultimately what allows the humans to defeat the invaders. Ask any software developer, and they will tell you that it is ridiculously hard to write a virus on a PC that works on a Mac, or vice-versa, and those are two computer systems that were designed and built by human beings. The likelihood of being able to successfully write a virus on a human-built computer of any sort that would affect a computer built by telepathic aliens is infinitesimal. Of course, this is an alien species that has managed to travel in huge ships across vast distances but has never invented a clock (hence the countdown timer they use before initiating their attack), so who knows what sort of vulnerabilities their computers might have?
