Hmmm I dunno, that's a tough one. I tend to follow the theory that an alien would be so strange to humanity that we wouldn't even have a basis for comparison...perhaps the alien is comprised based on a viral structure, perhaps the aliens don't die and so don't understand death and accidentally kill us by trying to communicate...etc etc etc. So long answer short (too late): Yes, I like space aliens, as long as they don't kill me or probe me in unnatural ways.
