Since we're talking DKR (pro or con), I have a purely factual question: Was this story the first to introduce the motif of tension/resentment between Batman and Superman? I seem to recall John Byrne touching on it (though to a much less extreme extent) in his reboot Man of Steel, which was from the same year I think. Just wondering which came first, or if there were other, pre-Crisis stories that set up Bruce and Clark as foils rather than friends, as I seem to recall their being in the Golden and Silver Ages anyway.
