Ha. Sci-fi is funny.

I love Websites that point out why things in Sci-fi movies don't work

But only as long as it give the movies the respect they deserve...

That being said, I've been bitching about the following one for years

"Independence Day" had already lost all credibility when Will Smith climbed into an alien spacecraft and after a few moments, figured out how to fly the thing. But dumb turns to laugh-out-loud ludicrous when Will conquers the aliens with a floppy disk, in an absurd homage to "War of the Worlds." Will should have just stuffed a peanut butter sandwich into the disk drive. It would have had the same odds of working.
