That's pretty much it -- you can't by any standard call Jackson's films "literary" which, for someone who appreciates Tolkien's works for their literary value, is obviously less than appealing. But, they're certainly "successful". Whether or not they're "good" remains individually subjective.

Even then, though, it's the ridiculous plot holes and hilarious geographical impossibilities his changes introduced that annoyed me more than any deviations from the book. They show the maps in the films -- we know the geography is the same as in the book, and yet... there are multiple instances where the sets are in blatant contradiction of what's shown on the maps, the paramount being the location of the Barad-dur and Orodruin within Mordor. And apparently Jackson's Morannon is a brisk walk across the Anduin, rather than a thousand-mile-trek northward along the spine of Ephel Duath.

...nevermind! Hyper-literate obsessive nerds are not Jackson's audience. Besides, he gets my money anyway just so I can analyze the films to complain about them. :p
