I don't think that criticismis that bad really, as long as it's done objectively. There are endless amounts of threads about Jon's voice, I for one think that Jon still has a very good voice and is one of the best rock singers out there but when you do compare him to the these days shows you really can see that his voice has been damaged a bit. which is understandable. The other thing is the music direction, I for one liked Crush and Bounce (OWN and TLFR are another story) but many fans don't feel those albums are up to Bon Jovi's standards and they are entitled to think that. They are the heroes to a lot of fans, even the ones who might feel dissapointment.
