I don't hold the original dear to me, I like it, wouldn't say I love it. So that's possibly a reason it doesn't bother me. Also I thought PJs while showing love of the original, was just entertaining as a standalone movie. As I said I am in no rush to revisit, it was a good entertaining movie, and somehow I have it on DVD, I wouldn't have bought it so I assume someone gave to me, and I haven't tried again.
For me Peter jacksons best is HEAVENLY CREATURES, but I haven't seen The Lord of the rings movies yet. Saw the preview for the hobbit the other night, I am sure it's fun, but it looked kinda cheap and cheesey.
