Matt Keil, a writer and producer of G4 X-Play, has posted in NeoGAF forums in response to Destructoid's PAX 2007 preview that "Mass Effect is disappointing, but nice looking". Matt has this to say:
Do not believe this preview. I had the first hour of the game played in front of me, and none of Destructoid's criticisms are valid. This is either truly awful taste or a pathetic attempt to get more hits. Possibly both.
Mass Effect has the most incredible facial animation of any game ever (at the time I saw it, anyway...Heavenly Sword tops it in cutscenes, IMO), and the voice acting is perfectly fine. The beginning of the game is all space navy "Sir, we have visual" shit, anyway. It's obviously not going to be Gone With The Wind.
There are plenty of things to worry about with Mass Effect without making up shit about the presentation. This preview is simply not describing the game I saw.
