Yes. Come on, this is not just anyone. This is like replacing Peter Jackson as director for a movie based on Tolkien's universe or a fourth Matrix movie that's not written by the Wachowski brothers. Star Wars is the brainchild of George Lucas and I'm not interested in third party literature or movies.
I kind of had the same emotions. To me, Lucas was Star Wars as well. But he's still going to be involved with the movies and the woman in charge with the new ones has worked with him a lot in the past. And it's great that George passed on the franchise on his own terms.
