I’m envious of you folks who like Doctor Who.
I generally enjoy science-fiction and am always looking for new content (novels, movies, etc.), but try as I might, I can never get into that show. For whatever reason, it just refuses to draw me in.
But on the topic of sci-fi, I highly recommend the “Culture” series of novels by Ian M. Banks. I’ve seen it described as “space opera for liberals.” I don’t know about that. All I know is that I love the series.
