There are some issues here. One of them is that the people who rate games are the people who buy games, and that's an effect of having a young industry. For the most part, there are no generational differences, few fleshed-out genres, and a very bland pallet of tastes overall. To say that gamers are more sophisticated than moviegoers is ridiculous. We're just a far more inbred group, and share a lot of common tastes. Once you get more diverse games, more diverse players, and get to the level where newspapers have video game reviews right next to their movie reviews, and the video game guy doesn't look like the movie guy's nephew, *then* statements like "Video-game consumers are the single most sophisticated shoppers in the entertainment industry" could be made.
But they'd probably be wrong.
