Re: Christopher Eccleston is playing Malekith
I thought Mal was perfectly fine. There were plenty of scenes with him, he was hell-bent on finishing what he started 5,000 years ago.
This is just a theory, but my feelings are if the DE's had spoken English the entire time, people wouldn't have said it felt like Mal was barely in the movie. There is something about having to focus your eyes down on the translation that is distracting from watching the characters on screen.
My only qualm with Mal was that they simply did not know how to utilize him during the fight sequence in the climax.
