I wish they would stop spending huge amounts of money on celebrity voice actors with no voice range...
I think Christopher Plummer did ok, but Joan Allen, who's a top notch actress, really doesn't shine at all in this game. She sounds like she's just reading down the list of dialogue, which is what the 'behind the scenes' video seemed to show. Granted, without any visuals or real context it must be hard to nail it, but I think less expensive talent could have done a better job. And anyways, I'm sure most of us didn't buy the game for the celebrity voices.
And besides that, the material is pretty bad. I mean, the story is fine, but the writing really isn't that impressive.
