先别吐槽这个改编是好还是坏。原文这么写的:
"Clark Kent's heroic tendencies would rise to the surface only when the threat was great enough. It would have to be a global menace — one that might also trigger an internal conflict about whether he belongs on Earth even as he yearns to be among his own kind. That's what pits him against General Zod (Boardwalk Empire's Michael Shannon), a Kryptonian tyrant who wants Clark to join him back on Krypton, which would mean abandoning his post as defender of the weaklings of Earth."
只是说要带他回氪星,《超人归来》里超人就会去过,关于氪星依然存在只是推测。
