I took the family to see the movie last night and everyone was thoroughly entertained by it.It certainly took me many months to read the trilogy over 25 years ago, and I can remember struggling to read it. (I'm still a slow reader even now!) The book was very slow in parts: not like the Hobbit that I had read earlier.
In contrast the movie was pacy, though I agree with Desdemona that at times the incidental music was intrusive and redundant.
The menace that was observed by the wraith-riders was exactly right. Bilbo Baggins transformation into the grasping monster seeking the return of the ring from Frodo was brilliant.
Gandalf was of course credible, but I was a little dissappointed that we did not see much of Golum (I think his role develops more in the next sequel).
Couldn't help noticing that Gimli seemed to possess a broad South Wales accent early in the film, which later became broad Scots!
The whistle playing sounded vaguely Celtic I thought, but did not at any time detract from story.
As DtG advised in the first post, I think its an excellent film but go see it and judge for yourself!
