I guess that makes her performance even more impressive.. Milla talked her senseless gibberish like it was her everyday tongue with rolling eyes, goofy grins, seductive smiles, and the don't mess with me look on "not without my permission". you could easily believe she spoke that language in real life.
if elfspeak actually is a language (and I'm willig to accept that), the LOTR guys knew what they were saying and should have been able to convey some feeling with the words.. they didn't get there, in my opinion. Viggo, Liv, and Hugo all appeared to be reading rather than talking, with no inflection or facial expressions to match the verbage (ok that's how Hugo always appears, but hopefully you get my point on the other two).
wasn't bashing JRR, just the poor execution by the actors...
