Of course. And in between, you have the people who just don't like cups of tea.... or something like that.
For example, I did enjoy reading Harry Potter... once. And that's really it. I won't get involved in fandom or all this other...stuff that seems to be still going on, because it was just merely enjoyable when I read it once and now have gone on to something else.
I do not really need to justify it. But, on the flipside, I also should not say, "You guys are STILL reading that? Hoid take it, read something REAL!" or something equally or more condescending. As the ol' saying goes, sometimes there's no accounting for taste.
