I love the 'Pet Sounds' complaint - 'it's mono!' In a related vein, there are quite a few 'Citizen Kane' reviews on Amazon that slag it for being in black and white (one reviewer whines that 'it's not even in color!'). And then there are the folks who insist that 'Kane' was filmed in widescreen, so how come the DVD is cropped? Some of the reviews may be tongue in cheek. It's hard to tell.
