Which actor or actress do you think deserves more credit?

I think Aragorn ought to be given lots of credit. He wasn't the original Aragorn they cast and so he had about a week between the time he was cast and he got on film. The guy that played Lurtz, because he had so much makeup and all. Gandalf because he was just perfect and could do everything he did well. Merry and Pippin becasue they are just perfect for the part. Personally I loved Galadrial. She has this elvish air surrounding her and has an awesome voice too. I didn't like Legolas (I'm biased because of the books), Denathor (He was played awesomly but when he eats I lose my stomach), Haldir (I'm not sure why), Eowyn (some of the parts bug me to death), Frodo (because all of his scenes are annoyingly slow), and finally Celeborn.
