From NY Magazine:

Video-game players — and critics — want GTA IV to be everything at once: They want the story to be Moving and Important and Consequential in the manner of Coppola so as to defend their medium. Plus they want to fire rocket launchers from a motorcycle while drunk driving. It’s unlikely that this combination will ever quite work — not just because of the uncanny valley, but especially because the balance of action to narrative is tilted so heavily toward blowing shit up.
