It's his worst received album for a reason.
Sub par songs
Sub par production
Poor song selection and sequencing
Songs barely sound like MJ songs
It's a good album, but it gets the treatment it does for a reason.
Off The Wall is almost universally loved and received. It has a couple of ths biggest hits of all time. Laid the ground work for the biggest selling albums in history which changed music/the world.
Last but not least... MJ didn't even think the album was worth promoting himself, opting to sing BOW, Dangerous and HTW at award shows/appearances between 2001/2002 instead of ONE Invincible track.
Also, MJ getting song credits on songs he didnt contribute a word to (Whatever Happens) is really crappy.
The outtakes are far better than the final songs.
