I think music journalists like saying this is the best Beatles solo album because they aren't really journalists in most cases, they are writers, and they like a story. The story of George, the poor put upon Beatle finally getting to shine is a good one and not wholly false. However, I think this album has its flaws much as it has its moments of genius. The production has the two problems of Spector being on the wane and George being too influenced by him and inexperienced as a producer, especially on his own stuff which is sometimes harder than working one someone else's stuff. I usually love big mushy reverberant productions but it gets a bit wearing here. I like the idea of a bonus instrumental album a lot but always get disappointed by most of it being Clapton infected blues snoozefests.
Having said all that most of the tracks up to and including Apple Scruffs are good to great with Isn't A Pity being the real standout and worthy of its double appearance.
