No, don't duck, Araréiel! Orli was wonderful as Legolas. Nevermind the hair color thing. His performance was soft voiced, he was light on his feet as we'd expect Legolas to be, and of course his work with the special effects crew was fantastic. To this day I still can't shake the picture of him hitching a ride, swinging himself up into the saddle in TTT. It was GREAT. I found all the secondary characters in the movies wonderful - and Sir Ian was great as Gandalf. I've got a few itchy points with Elijah, though, and the recharacterization of Faramir irked me greatly.
I didn't use the movies to color my imaginations of Tolkien's world. I already had that in my head. I will say that the scene artists, the armourers, the silversmiths, even the makeup artists all had the same image that I did, and I'm thankful for that.
I still walk in Doriath in my dreams, though. *sigh*
