Do professional reviews really matter?

... keep in mind, that professional reviewers are to some degree dependant on the companies, whose products they review.

I often find specs, handling, IQ nicely discussed by professional reviewers and I love the comparison tool of dpr to form my own opinion on image quality.

But for built quality there are no real citeria and the dpr ratings for it seem to be directly proportional to the amount of metal used in a camera body. The facts about built quality I learn from amazon reviews with less than 5 stars.
