No way it's the best. It was very good, better as I reflect on it - IE the long drawn out betrayal sequences. But there weren't any great moments like, say, the one in Empire Strikes Back just before Han gets frozen. The characters are much more one-dimensional than the ones in the original trilogy. Some of it was still just silly.
But it was good. And anyone who wants to see had better get himself to a theater soon because I don't see how you can really spoil a movie where everyone's known the ending for twenty years.
