I am both sides of this. When I first heard Invincible, I did not like it at all. My reaction was similar to earlier comments, I don't see much of Michael in it, not his best work, etc. etc. But after listening to it 10 times I realized that when I first heard it, I was in Thriller/Bad/Dangerous mode, so I was expecting the same type of songs. But this was different era, Michael was at a different place in his life, he did not even write most of the songs. This was not a album that you start playing and start dancing, this was much more sit down and listen type of album. I can also Invincible not appealing to the 20 year old me, it has so much emotion that my younger immature self would not have appreciated it. Now I LOVE Invincible and listen to it way more than others.
