I agree he intends to make a good film. I doubt very much he would have considered the project at all if he didn't think he could make it great. I think a lot of it is when you love something so much and are very close to it, you run the risk of failure because of trying too hard to get it right.

Being to close can also have it's benefits. It could make him know what belongs in a Star Wars film and what doesn't. It could also lead him to know what experiments or risk he should take and ones he shouldn't.
