Its worth remembering as well that Tolkien himself was fairly dismissive of TH, and that it only really touches greatness towards the end. Tolkien disliked the tweeness of the start of the book and in the early 60's attempted to rewrite it in the style of LotR (and failed, btw). It could certainly be argued that Jackson's version, so far, has treated Bilbo's story with more respect and dignity than Tolkien himself did...
