Here's the perfect example of how Amazon's policy of cross-posting reviews between different releases of the same item is a bad idea.
Nearly one-sixth of the reviews for this excellent Criterion release of an excellent film give it one, two, or three stars. Of the more than 50 one-, two-, and three-star reviews, all are for crappy public-domain releases from such respected and well known distributors as A2ZCDS, Delta, and Madacy. What? You've never heard of any of these companies? There's a very good reason for that.
These unfavorable reviews for what is essentially a different product unfairly drag down the star rating, and this is not an isolated incident. Please, Amazon, stop cross-posting reviews, or at least give us the option to filter out reviews from earlier versions of an item.
I agree 100%. I recently wrote a review of the Blu-ray version of The Ten Commandments. You'll be lucky to find it because it's buried within the 400+ reviews of the DVD. Amazon has this policy that once a review is submitted by a reviewer, any future reviews of the same movie is given the original submission date, even when the old review is deleted and a new one is created. Brilliant.....NOT!!!
