I remember after IW there were a lot of reviews complaining that it was a cheap trick to tug the viewers' heartstrings by dusting beloved characters on screen when the next movie would just bring them all back and undo the whole plotline. I guess the head honchos thought the way to answer this criticism was NOT to undo the whole plotline, but just halfway undo it... which misses the point of the criticism, which is "this storyline was designed to wring cheap emotion out of the viewers and it was a bad idea in the first place."
