Why I Hate Crisis: This Says it All

Before the Crisis, Krypton was a place of marvels. There were the Crimson
Jungle and the Thoughtbeasts and the Fire Falls and the Jewel Mountains
formed from the skeletons of extinct birds and a thousand other fantastic
details. Its people were human; they struggled and fought and lived
and loved and dreamt dreams petty and magnificent. Superman's exile from
his home was a genuine loss.

After the Crisis, Krypton was a sterile world without wonder. Its people
were soulless automatons; its destruction almost welcome. Superman's exile
became a rescue from a fate worse than death.
