It's weird. For me, the most important ingredient in these prequels is Lucas. If these came from anyone else, they'd be "fan fiction" to me.
It's the Lucas x-factor that makes these so interesting. We puzzle endlessly over why he did this and that. But HE did it, and that makes them interesting.
I've never been able to enjoy the "extended universe" stuff. The Timothy Zahn novels felt wrong within a few pages and I stopped reading.
"Remaking" these would probably work for me if the original story was kept and simply made more dramatic (i.e. have the Jedi Council actually DO stuff, have consequences for Qui Gonn's defiance, maybe reverse the TPM dynamic so that everyone EXCEPT Qui Gonn thinks Anakin is the chosen one instead of making Anakin a jedi even when EVERYONE correctly thinks he's bad, etc.)
The way things are going, I bet we can expect some pretty decent unofficial remakes within 20 years. That will be interesting.
