Check out Fakespot.com. you plug in an Amazon URL and the site will analyze the reviews/reviewers and give the product trustworthiness score and an adjusted 5 star rating. I've had pretty good results with this. I started using it after I bought a couple of VERY highly rated books that were just unreadably bad. I checked them on FakeSpot and they all had abysmal ratings when the fake reviews were removed.
