As you can see PK, there is no such thing as Heresy at this forum

. We have a whole bunch of different opinions, and agree on some and differ on others.
Personally I thought Sam was brilliant, but I see what you mean about the odd condescending glance at the beginning. I just took it as the look a "servant" might give his "master" when he thought "master" was off his rocker

. So it worked for me, but I can see how that might annoy.
Tar-Palantir, I don't think I agree that the Orcs were feeble, they seemed right on the mark to me. Some varieties were definitely not as rugged fighters as others, but they were still pretty creepy and scary-looking.
Funnily enough, I actually found Boromir's death more moving than the book. And he seemed a more sympathetic character to me in general (not to say I think his basic character was changed, just a different emphasis on certain aspects of his persona). I don't think he truly realized until that moment Frodo disappeared, the Truth of the Ring's "altogether Evil" Power.
Whether one agrees or not that Boromir of the film was like the book, I think his performance was so convincing I forgot it was a performance. And really, though I concede it's debatable how accurately the film characters in general reflect the book characters, I think the casting was, on the whole, brilliant and all the performances were convincing.
