I think the hype for this movie is serving to spread awareness of who and what Bane is. He is Batman's physical and intellectual equal. Joker and Batman in a straight up fight, pshhhh
 knockout, 10 seconds in. Even Ra's fell to a fairly "wet behind the ears" Batman. 
 
Bane is a better villain, IMO. Hardy is a better actor, IMO. 
 
Consider the excitement that surrounded TDK. Would that excitement have existed if BB wasn't great? BB was about Batman/Bruce Wayne. The mainstream didn't know who Ra's was. To me TDK focused too much on the Joker, Dent, and the mob. I think rises will have Batman at the core, and villain/sidekicks where they belong, as supplements to him. Don't get me wrong though, based on the prologue I think Hardy will match Ledger's performance, but it will serve Batman's story, not Batman serving the villain's. Just my opinion.
