That's like saying TDK sucked because Batman never ran into Joker in Batman Begins even though he was in the city.
They should have. When you start a movie, especially one that you know is going to be a franchise, you need to set these things up. Batman Begins set up the Joker. It felt a bit rushed, but at least they did it.
Also that's not a fair analogy. It would be more like Ra's Al Gul's previously unmentioned boss showing up in TDK, not a new, unrelated character.
