Firstly, there's a good chance the existing reviews came from those who were alive when this album was first released, so I don't have that experience and perspective under my belt-- but I can say the remastering is impressive, done by John Davis and none other than Stephen Street himself. The tracks seem truly revitalised as if new life has been breathed into them, if the best sound is what you want this is the version to get.
As for the 'replaced' track, I can understand why people are upset about 'The Ordinary Boys' being omitted and replaced with an unrefined track from the Viva Hate recording sessions-- but for me, the track lends itself much better to the mood of the album (and it's far more 'Mozzy' than 'The Ordinary Boys'). It is a shame Treat Me Like A Human Being didn't originally get the spot it has now, and that it wasn't developed beyond its current state. You could make the argument that removing the track tampers with a masterpiece, but if it is the original you want it is readily available.
The only 'unfair' complaint I could make is that it lacks something 'extra' to celebrate itself, much like how the 'Your Arsenal' and 'Vauxhall And I' remasters both included a live DVD/CD respectively-- I feel that is where this and the 'Kill Uncle' remasters (especially 'Kill Uncle') miss the mark. But as far as the CD itself goes I can't really fault it.
