In reply to:
My biggest complaint is that whenever I hear Hugo Weaving's voice I expect him to throw in a "Mr. Anderson" here and there. (The same thing happened in the Lord of the Rings movies, too.)
I actually didn't think Hugo sounded like Mr. Anderson as V. He had enough accent and tone change in his voice to make him not sound like it. I dunno, I thought he did a very good job as V and not making it sound "like" Hugo as much.
Also, The Wachowski brothers just wrote the screenplay, so, I don't know if they had a lot to do with the special effects.
