I still think that Gollum was really irritating. I can deal with manic characters in books, but not in movies or television. Or in person, for that matter.

The changes to Faramir didn't bother me so much.

The movies fail to capture the mythic tones of the books. They try, in parts, but it's undermined by the effort to "humanize" the characters.

I haven't had any particular urge to watch TTT, though I watched FotR a few times. I'll probably get and watch the extended edition, mainly because I enjoyed the commentary tracks and extras on the first one a lot (in fact, I've never watched the extended edition with the main audio track).
