Yes I think it certainly is interesting to find how something like watching another person's interpretation of the story can impact your own, even when you are already familiar with the story. I didn't have the same experience for Harry Potter as I didn't read them until after the final film had been released, so the movie franchise was my first exposure to the universe. I think far too many modern protagonists are written to be a heroic character, rather than being someone who steps up to heroic actions despite not being what you may consider to be inherently heroic. This is where Bilbo shines for me!
Agreed.
Actually, I read the Harry Potter books before I saw the movies, and must say that I liked them a lot.
The strength of the later books is how the back story is slowly added, incrementally, layer by careful layer, over the entire series.
While the sixth book gave us Voldemort's back-story, (and the inevitable death of Dumbledore - the Guide - or Mentor - is always killed, or otherwise removed from the plot - as was the case with Gandalf - so that the Hero can grow into his (or her) Destiny), I did wonder what the seventh would - or could - possibly reveal that would have an effect on the overall narrative.
Very often, in fantasy, the final work is among the weakest of a series, and can often be a massive disappointment, as it fails to deliver on character, development, narrative and tension.
However, J K Rowling delivered a stunning tour de force in her final work, and brought it home in style - personally, I think Deathly Hallowes the best of the series, and the double back story that the book told us, the stories of both Dumbledore and Snape, lent it a real narrative heft and power.
I looked back over The Sword of Shannara recently, and found it shallow, whereas I had loved it when reading it as an undergrad - oops - a few decades ago, in the 80s.
