It's certainly made me think more about what I've been reading, as has sea_bright's comment that I didn't seem to expect to like most of the books I've reviewed. In fact that was more-or-less by design: faced with such a wide variety I decided to make the most of it. Before the holiday my reading had been dropping off. Though I enjoyed the books I did read, there weren't many that enthused me enough to give them a go, so I made a conscious effort to use Reading Week to recapture my enthusiasm and broaden my horizons. Obviously, since then I've been spending my spare evenings reviewing rather than reading, but at least the enthusiasm has returned. The horizon-broadening aspect has been less successful, though. If anything, I reinforced my ideas of what I enjoy and don't, which I suppose is useful even if it wasn't really the plan. For example, most (but not all) of the books that I enjoyed most have a sense of humour: not that it's very surprising that that should be a quality that I value. More significantly, though, I confirmed that my tastes lie in the direction that they always have: weird books. I don't much mind whether it's science fiction, fantasy, horror, or one of their many cross-overs, subgenres, mash-ups and hybrids (call it speculative fiction, for want of a better term). The important thing is that it's not realistic.
What I'm looking for is the unexpected. By way of counter-example (and with an apologetic hat tip to sea_bright for picking on her favorite genre), consider crime fiction. I'm occasionally lured into reading some by an intriguing premise on the back cover, but am almost always left disappointed. Typically I like the set up of the mystery ('Who is killing people and leaving little dolls by their bodies, and why?') but the resolution is invariably disappointing ('It's a murderer. He's doing it because he's mad.') But of course it's a madman! It literally couldn't have been anything else. In weird fiction, there could be any number of explanations: sinister rites, aliens, time-travellers, anything. That's not a great example, I grant you, but hopefully it illustrates my point. Essentially, I suppose, I'm interested in plot over character, and speculative fiction offers a wider range of plots, or at least (if one accepts that there aren't really that many to be had) a wider range of possible twists. That also explains why I'm less fond of 'straight' fantasy, space opera or whatever, because they can often feel, in their ways, as limiting as any other genre. And, while I'm at it, suggests an explanation for my aversion to spoilers, and rewatching things: ruin the surprise, and you ruin the thing I would otherwise have enjoyed most. Ironically for someone who's spent his last ten evenings sitting on the sofa blogging, I'm a neophile at heart.
