I think the shortcomings of the prequel scores, particularly II and III, have more to do with the movies themselves, Burt's role, and Lucas's insane editing/reshoot issues. If Williams were given the opportunity for episode VII, I think we would get a score closer in spirit to VI versus I-III due to the nature of the movie and production team.

For those who complain that Williams's interviews are always the reiteration of the same talking points (and there seem to be many such people), you should listen to this interview.  Williams gives excellent insights into his approach to composing for Lincoln, particularly in terms of early American music that is just wonderful.  And, damn, he literally sounds like his is a vibrant 60 year old.

One of Williams's great gifts is the ability to compose engaging melodies.  At this point in his film (though not necessarily in his concert) career, the basic framework for orchestrations seems set.  Producers, directors, and even his own sensibilities are not going to allow him to re-invent the wheel.  However, one the things I look forward to are his melodies, which tend to be original, and based on the samples of Lincoln seem to be original and engaging.  To expect much more than this in terms of originality is just not reasonable, and, therefore, to be disappointed that Lincoln does not break the mold in the considered sense is just not reasonable.

However, if there is any doubt that Williams the artist can compose truly inventive music beyond just new melodies, I would recommend you listen to his concert works, particularly his La Jolla Quartet or even his piece for solo classical guitar.
