^ Well, I think it's the difference between remake and reboot. I don't mind the idea of a reboot (even if we have far too many of them at the moment), but the idea of a remake usually feels pointless to me.
I'm okay with Nolan's Batman films because he didn't set out to remake Tim Burton's movie, but to do a completely new take on a character that's a modern version of a mythical character (like how many different Greek playwrights and poets would make stories about Herakles).
It's the remakes that basically tell the same story just with different actors and updated special effects that feel pointless to me. It isn't a perfect example because it is based on a novel (though the movie was marketed more as a remake to a classic film than as an adaptation of a classic book), but a recent example would be Ben Hur. I felt like there was absolutely no reason to make that movie when the excellent 1959 version, which still looks amazing, lies within reach.
So, bringing this back to Star Wars, if at some point in the far future the current Star Wars canon has lain dormant for many years and someone wanted to do a new take on Star Wars in a completely different continuity, I wouldn't have an issue with it, but if someone were to remake the film The Empire Strikes Back, I would think "Well... we already have that movie and it's amazing. Why make it again?"
Where sky and water meet,
Where the waves grow sweet,
Doubt not, Reepicheep,
To find all you seek,
There is the utter east.
