That does make sense. I was telling my sister recently how I was unable to read 1st person just now, and then we spent a while discussing a really well-done 1st person series. I think the thing is that to work well, it needs a really clear character voice. And I've been reading a bunch of fanfic, and most people can't pull off that much constant character voice to do good 1st person fanfic. But even the original stuff I've looked at lately in 1st person, I'm just like, "Do I have to listen to this one character telling me everything? Whyyyy?" But it's something I've only recently noticed, so it's probably just a temporary mood.
