Science fiction is really broad. :3 It could be space based...experiment based...virtual reality based...hmm...alien based or set in the future. There really is a lot of avenues people go down. Some people put too much thought into concepts though and that's a turn off for me. Sometimes you don't need to know how every lil dodad works. I've had people nitpick some technology to no end, who I assume were science majors. Haha.

What about sci-fi piques your interest?
