Any ST Lucas would make would suck just as much as - if not more than - the PT, especially since characters from the OT would undoubtedly feature in it and suffer character derailment in the process.
Imagine CGI Luke bouncing up and down like a goddamn rabbit on speed, twirling his lightsaber like some luminous green baton. I wouldn't want to see that and neither would you.
The story of the ST exists for me in the EU. If I want to explore the trials and tribulations of the fledgling New Republic and their victory over the Imperial remnants then I'll read some books and comics penned by better writers than ol' Georgy Porgy.
