I tend away from discussions about reused plot points in Star Wars, (Previously I did it with EU material, now I guess I'll be doing it with TFA) because it all seems a bit pointless to me.
Take A New Hope. It uses the granddaddy of cliched story-lines, (Farm Boy saves Princess from Black Knight/Sorcerer's Castle) and it worked very well. That's one of the big things that made ANH great, it took a story-line you'd seen and did a new spin on it. As long as TFA does this, (I haven't seen it yet) and does it well, I'll be okay with it.
I don't mean to be rude, but some of the EU is... messed up. Take for example the Jedi Prince thing that technically was still canon. Apparently somebody thought back in the day that the jedi must have some weird monarchical hierarchy. That series also introduced the Emperor's three eyed, mutant son, (Frankly, I don't want Sidious and procreation in my mind at the same time; It makes me shudder.)
I miss a lot of the EU too, but when people say they want EVERYTHING back, I just have to mention that.
