I didn't think Golum was that bad! He was brilliantly animated (yes I know there was an actor standing in for it), he didn't look fake or out of place at all, he had a consistent look thoughout the whole film, his voice acting was very good, and it was the only real character, it was the only non-bidimensional, fake, horribly acted character. While the rest of the actors looked like bored grade school kids reading from "Richard the Third", with characters even they didn't know about or didn't care, Golum/Smeagol was a real character with real reasons for his behaviour, with real emotions...
