I agree. An example of poorly edited/directed death scene in this series would be Gambol's in TDK and Foley's in TDKR.
God, Gambol's death makes me facepalm to this day. There is absolutely no cohesive sense of cinematic space within the stretch of time from the Joker knifing his flanks and bringing himself and his knife (what happened to the other one?) to Gambol's face.
