I loved Arwen's expanded role in the movies, and I loved liv Tyler's portrayal of Arwen. I thought it was great they made Aragron's true love a courageous shield maiden in her own right -- big plus for me. It was too bad they didn't have time to develop the books on screen so Elrond's whole family could have had their due, but I have no problems with Arwen. I thought it was terrific what they did with her role.
