TDKR will do well at the BO, but to do GREAT, i mean, TDK great... It must be liked by the audience. I mean REALLY liked. Thats made by the same people and continues the story of TDK makes it reasoinable to entertain the notion that it should do similar, but in the end the reason Avengers is an unexpected jugernaut is beacuse people LOVE it. As nobody has seen Batman yet, that WOW factor that propulses from good or great to jugernaut in the box office is, as for now, a big question mark.
