The Narrator has an incredible voice, I absolutely love listening to her. .
Mh. I like the actress (and she was great as Malady) but I don't think she's particularly fit as a narrator and in fact I think I preferred the old man they used for DOS 2. Brian Bowles, according to IMDB.
I don't doubt personal taste may play a big role in it, but her constant overly smug/malicious tone doesn't seem like a particular good fit for the role of "teller of the story" to me.
