My main complaint with Bon Jovi is what happened after CRUSH.

I don't really like the album Crush, and it has way less depth than TD or DA. But it is ok - pop oriented, laid back, and yes ok It's My Life was a cool hit to happen.

After that they became more and more less and less original.

They repeated themselves extraordinarily - to the point of hinting to self-sarcasm at times (I am sure this was unintended ).

I don't think so mich dumbing down of the new music was needed. If they would have been a bit less trying to score same type hits, they would still be miles ahead of their 80s colleagues and fine business. They were huge in touring anyway.
