Roger Ebert recently retweeted an interview with author and critic Camille Paglia (her Wikipedia page) wherein she talks about Lucas and ROTS in particular:

She also wrote a fairly lengthy essay (which can be found in her new book, unread by me) declaring G.L. as the greatest artist of our time:

I doubt she's going to be invited to the ranch anytime soon but I enjoy her insights. I think her comments may be among the first in mainstream criticism to re-evaluate George's work and contributions to the culture post-ROTS in a positive light. It'll be interesting to see if more of this stuff emerges the closer we get to Episode VII.
