I love conceptual sci fi art of buildings or structures and landscapes. Ofcourse the sci fi character designs, hovercrafts and so on is nice to look at, but i find it alot more interesting if it's all put into one big piece without being insanely detailed. ("Detailed speedpainting" i guess you could call it )
It depends. I can't say I like ALL sci-fi art, and I'm not so into mechas, space fighting and other 'cliche' sci-fi stuff persay. I personally prefer fantasy and a lot of times for art I really like classic portraits. Don't know why, they just appeal to me.
I like it... In a way. The badass sci-fi, that is. Star Trek is funny, yes, but it just doesnt really overwhelm me. While the fun thing 'bout sci-fi is that there are so many things to consider, technical and alien things... These things basically make the possibilities endless.
