Sensawonda...that's the word! Those books (to me) seemed rather "joyous" about exploring the universe and meeting new species. I haven't really been looking at the new SF that's coming out now. I got rather discouraged by all the "gloom and doom" or people's "issues" that I found the last time I looked. Either that or there's nothing original and the work is just...ho hum rehashes.
Now I'll have to go raid the old library again. Just can't beat that "sensawonda!"
And LotR has that same sense, doesn't it? Just because it's about Elves and hobbits doesn't mean there's no wonder - but I can't think of many other fantasies that are the same way. I think it's because LotR is closer to the original myths and fairy tales than the books that are basically derivatives of LotR. And science fiction is, in a way, a new sort of myth, so it would have that same sort of wonder about it.
Although I think man ought to follow his dreams, sometimes I think we ought to be careful exploring space. What if we find a species that removes us from (our perch at) the top of the food chain?
I love Sci Fi too, but find much of it pretty juvenile these days. I was easier to please 25 years ago. Somewhere in FR, I think there's a thread posted that recommends authors, does anyone know where?
