In all honesty, I fear it would be wishful thinking. I might have joked in my earlier post, but in fact I do suggest having a reasonably skeptical approach to whatever one reads (not only game reviews).
Part of the problem, I think, is that there's the expectation that game reviews will be written by journalists, while it's not a journalistic job at all. A review is a critical work of deconstruction and analysis, and the person doing the work must be deeply intimate with all the aspects that make the final whole. Other, more established crafts, like film, music or literature, are criticized at a level vastly superior to what we have in games media. Still, since what general gamers public wants are essentially buyer guides, that will never change as long as there's no demand for more serious, in-depth works of critical thinking.
