Since most sci-fi isn't sci-fi at all I couldn't care less. It seems that the industry decided to call everything futuristic: sci-fi, no matter if it could be something we Could have in a hundred or thousand years. For example, star wars is called sci-fi even though most things in there contradict science. And.. they even added some religious crap to it (the force) making it even less sci-fi (not saying star wars is bad, just saying it's not sci-fi in the original meaning of the word).

Shortly, sci-fi is a term most use to cover all futuristic works of art.

Secondly, we wouldn't get as many sci-fi titles if all creators had to consult with scientists before continuing, and that would be very sad, not to mention that scientists have more important stuff to do (doing real science) than to be consultants to writers/directors/etc.

Thirdly, "laws are meant to be broken", often it's just more fun to go outside the boundaries of science. The ragdolls for FEAR, how hilarious wasn't that? You're meant to have fun playing games, so I guess if the game is really boring then you could start caring if it's correct sci-fi or not.

If I want a true sci-fi story, then I read a book.
