All that stuff is cool at some point but seeing guys in their late 50ties or 60ties dressed up, jumping up and down between flames and doing acrobatics in the air is just ridiculous IMHO. Only KISS can pull it off but they've been clowns doing a theatrical act for ages.

As for more rock sound I'm all yay but we have to take into account that Jon's voice is not what it used to be. It's not trashing him, it's just coming to terms with the reality. What they are doing now is balancing between current situation and fans' desire to hear old hits.
