I think the Star Wars movies are classics, and I do like them, but if we're going to go on how "advanced" or "cutting edge" the movies are, the new ones are going to disappoint regardless of who's directing them. They'll never replicate the first three because they were so different than everything else that was out there at the time - CGI is common now. In any case, I feel there is a lot of room for improvement after the three newest episodes. They were mostly <7/10 on IMBD the last time I looked, so Disney could definitely improve on George Lucas if they do a good job. It's not like Disney only makes animations. They've done all the Pirates of the Caribbean movies, Tron, Prince of Persia, Remember the Titans, Narnia, National Treasure, etc. JJ Abrams is directing it, so if you want to see an example of what it's likely going to look like, look at the Star Trek movies. The biggest problem Disney will have is moving past the whole Darth Vader meta-plot, which is synonymous with "Star Wars" now even though his story has ended.
