Query: Bitter Disappointment

How far they have fallen! I have the two disc set of each of the other movies (1- 6) and expected the same quality from this one. Instead, I got a poorly filmed, poorly written DVD that is a bitter disappointment. And what is this business that only Walmart sells the two-disk version? Not everyone shops at Wally World or cares to do so. I resent being forced to shop where I don't agree with their corporate policy. Had 1-6 been sold this way, I could understand it but they have simply downgraded their product without warning the buying public. Poor business practice and it'll come back to bite them in the @ss. Don't you just love surprises like this? You find the product inferior but you can't return it? Not good for Amazon's business either!
