Whenever someone strong in the force appears, it's always "oooh, they must be related to Blabla WHatshisface" or something like that, because people are so bloody unimaginative.
Heehee. This amused me more than I can really explain why. Blabla Whatshisface. *snerk*
I'll take your word on the EU doing that a lot. I didn't read much of it, because most of what I read was junk. But, thankfully, since Disney has dumped most of the EU, you might not have to worry about everyone being the Force child of some awesome Force user going forward.
Let's just put it this way: It would be rare to find an EU book/comic/whatever that A: didn't include someone from the movies (boy, those people got around!) or B: had someone that was directly related to someone from the movies.
