I just realized that The DARK KNIGHT RETURNS came out before SUPERMAN: The Quest for Peace and may have been a contributing factor in the low box office of the other. We know now that The Dark Knight Returns caused a significant hit to Superman's popularity at that time could it have influenced the overly negative reception of the film as well? Maybe even some of the production woes? Never really had reason to put two and two together and connect the two till I was thinking about Superman's popularity verses Batman's and the Switch during the 80's. It's not like people didn't have good Superman material during that time what with Ruby-Spears, Superboy, Lois and Clark, STAS and Smallville so what happened.
