I don't really have an RPS squick, but I do have a lack of caring for the canon. Basically, I'll read the RPS for fandoms I'm reading (i.e. Star Trek reboot got me to read Chris Pine and Zach Quinto, current Glee obsession is getting me to read skintightsock's Darren Criss/Chris Colfer fic... partly because she writes awesome and awesomely funny smutty stories, and partly because I currently have one of those vaguely-embarrassing crushes on a celbrity I will never meet Darren Criss, stop being adorkable) but I don't last long. Even popslash was only a flirtation for a few months.

Mostly, I can rewatch an episode of something over and over and love it every time. But if I watch too many interviews with actual celebrities they feel like real people and I have very little love for most real people. (There aren't a lot of people I could be trapped on a desert island with and not want to kill by the second day. Not for food or anything, but just so I didn't have to constantly spend time with them. I handle people best in short bursts.)

But, what I was actually going to say, is if you want the feel/style of reading RPS without it really being about real people, there's a Glee AU set on American Idol which really hits both of those. I mean, the Idol judges are there but the story is all around fictional people, so it's not really RPS just a real-place setting. I can find the link if you want/haven't read it.
