One Star?! For what might be the greatest performance of the greatest music ever written?!
If the sound quality is so overridingly important then one would be better off listening to the latest Kylie Minogue record instead. Perhaps, judging by similar criteria, 'Miss Congeniality 2' on Blue-Ray deserves a higher rating than, say, Buster Keaton's 'The General' on VHS, or a nice crisp print of Chris Moyles's new hardback should get a better review than a cheap, dog-eared paperback of Great Expectations.
