Who can keep up with the EU? It's an industry unto itself.
Like most people I have read the cornerstones--Splinter, Zahn trilogy, Dark Empire, and the radio dramas and movie novelizations--but other than odd things here and there I have stayed clear. The cartoons and some of the video games are maybe the exception, but even then I'm two seasons behind the current show and haven't played a Star Wars video game since the Lego ones.
When I was a young teenager I was more into it, I suppose, I know a lot of the 1990s EU but not much after the prequels started coming out. I don't know if there is an age demographic for EU, but I feel like there is much less adults who are into EU compared to the amount of adults who simply watch the films. Am I wrong in getting that impression? Maybe it's partly because most of the EU books/comics aren't particularly well written, but even the idea of EU doesn't interest me anymore, and most of the EU I've been exposed to has been fortunately pretty decent.
