I do get it, no idea why everybody now starts explaining the story to me like I misunderstood it :) Its fine that person A likes object X, but person B doesn't, there is no rationalization needed since it won't change the opinion.
I went for that sci-fi book for the space and sci-fi parts, and found the other side not interesting. That's it. I think I generally like sci-fi happening in space or generally futuristic. For medieval I prefer reading fantasy (which I think would help story tremendously if included for folks like me, since there is already another 'magic' in that universe).
