I'm detecting an undertone of "poor, unfairly treated Morrissey". But critics are generally pretty kind to him, except in the case of List of the Lost, because it was beyond awful. World Peace was pretty weak for a Morrissey album, but it got better reviews than it deserved (IMO). Morrissey does get criticised a lot for his behaviour, but that's another matter.
I like the Manics, but there's no denying not everything they have put out is genius. What do you expect for a band that's been together for getting on for three decades? If you don't like it, listen to something else. Personally, I'd rather see a band like that just make the records they want to make, rather than just pointlessly re-treading the same ground.
