What do I think of Sci-Fi?

Personally I believe science fiction is kind of dumb. The thing about sci-fi is that people then to believe it way to much. For example, the whole 'aliens in outer space deal. Oh please people get real. Don't you think that if there really were aliens that wanted to destroy us they already would have? Now don't get me wrong, some of the sci-fi stuff is actually OK. I thought the whole concept of I-robot was pretty fascinating. Really it's the stupid alien invasion stuff that gets me. Also, since we're on the subject, I think sci-fi is better portrayed in action rather than in writing. I get bored easily with the books but put it all in a movie and I'm like "Wow!".
