Under-rated? Yes

Poorly promoted? Yes
But, a great album? It's mostly not for me, except a few tracks (Unbreakable, Heartbreaker, 2000 Watts, Threatened and Whatever Happens). It's far too long and has so many ballads - most pretty weak, IMHO. As a review when it was released stated, it is over twice as long as Thriller and has less than half the effect.
I do listen to some tracks time-to-time, but it's not a classic.
I know I'll get attacked by people saying it is an amazing album full of heartfelt ballads etc., but there we go...
