Poorly thought out premise

Rating: Null/10 (7 March 2003)

WARNING: SPOILERS AHEAD.
I think this movie's premise was poorly thought out, and very unrealistic. To name just a few absurdities:
Any civilization advanced enough to find us and travel here wouldn't need to use crop circles as signs for communicating among themselves. And their method of communication would probably be a lot more private/secretive than that! I mean, really, give us a break!
Also, there is good theoretical evidence that water is essential for advanced life, not just here on earth, but everywhere. That's just a fact of life about chemical bonds and evolutionary forces, etc.. Those aliens must have circulatory systems, which would almost certainly be water based (some form of liquid 'blood'), as would their body cells, etc. And so, why come to a planet that is 75% covered with water, which could be detected from a great distance away, and which has an atmosphere filled with water?
Also, such an advanced race came here to harm/abduct people, but they can't fight their way out of a kitchen pantry? What, no ray guns, etc? Come on!
In short, this film was written by someone who seems never to have read any science fiction at all, or studied any science, or even given much logical thought to the premise or structure of the screenplay. What a disappointment. What a waste of two hours. Unfortunately, I saw it on Pay Per View cable TV, so I can't get my money back. But if I had seen it in a theater, I would have demanded (and probably got) my money back.
