Personally I like the movies better for a couple of reasons.
While the books have such detailed world building (Which is great) I feel like Tolkien focuses on that too much and that bogs down the book and makes it more like reading a history book.
The movies managed to keep the story moving with out losing the spirt of the books which I find very impressive.
The ONLY reason I do not like the movies is because it is really obvious that the character's don't really know what they are doing with swords. (That's just my opinion thought)
