I also think they're doing a bit too much tbh. It's a great album, but I ain't sorry ( ) for believing it certainly isn't better than Ray of Light, Vespertine, all MJ & David Bowie albums, Miseducation, etc. (according to pre-00s Metacritic score estimations taken from here.) Even the idea is just silly.
It deserves an 80 if I'm generous, although that's just my opinion.
Imo its better than all of the albums listed above
