I had a hard time accepting the Tolkein version of elves, which are vastly superior to humans in most respects. Tolkein's elves were tragic creatures who engaged in a futile struggle against the passage of time ... and based on the movies, I believe they were also very good at cobbling shoes.
Well, they talked cobblers, which is perhaps not the same thing.
I struggled to take Hugo Weaving (Elrond) seriously in the film, trying not see him as Anthony "Tick" Belrose in Priscilla, Queen of the Desert. I was expecting him to burst into a drag act version of Abba at any moment.
