Of those that have seen TDK, what are your thoughts on a sequel? Would you be satisfied if they don't do any follow up films? Personally I'm satisfied with where the story currently lies, And I'm also concerned that the studio may want to keep churning out sequels given the success...which could lead us back into Joel Schumacher territory at some point. Granted that's a worst case scenario [in my mind].

If all the same, key people are involved then I'd welcome it. I'd be happy if this series could be rounded off as a true trilogy.
