Of course his reputation as a filmmaker is in the toilet after the Prequels...even if I feel it's totally unwarranted...and if you look at the dregs that Hollywood puts out year in and year out compared to the Prequels.
And as for the credit for the Originals, it actually works in reverse now. It seems the on going thing now is to take credit away from the guy just because of what people think of the Prequels and that's totally unfair to do so.
Where's the balance with this guy? To me, he's never been infallible. But compared to a lot of people in the industry who think they know cinema, the guy's got them dead to rights....
I mean, criticize him for his writing and directing, which he's well aware of (even if everyone tends to go overboard in those two departments) but think about where cinema would've been had this guy not continued to push...
