Query: Dammit Amazon, Seperate Your Product Reviews Already!

First off; I have not purchased THIS PARTICULAR version of this all-time great film, however, I do want to purchase it for a friend who has bluray. The problem with this particular release is that the bluray version seems to be a terrible transfer. My real issue here aside from the fact that Warner Brothers continues to foist garbage transfers on an unsuspecting public is that ONCE AGAIN, Amazon.com refuses to separate it's product reviews, so it is simply IMPOSSIBLE for me to ascertain the quality of the DVD RELEASE vs. the BLURAY RELEASE.AMAZON.COM, if you are going to continue to provide customer reviews, PLEASE STOP mixing reviews for separate products together; The QUALITY OF INDIVIDUAL RELEASES IS DIFFERENT AND AFFECTS THE CUSTOMER'S DECISION TO BUY!
