He was sloppy.
In Superman (1978), Lex Luthor goes through pains to make kryptonite to use against Superman. In Superman II (1981), you have those 3 Kryptonian baddies {General Zod the icon, Ursa, Non}, & it doesn't occur to Lex Luthor to make a new batch of kryptonite, or dig up some of the kryptonite he made in Superman, to use as a control over Zod & his 2 best friends. And I don't mean Zod's friends in the Winnebago.
Very sloppy of Lex Luthor.Instead of Zod, Ursa & Non being Lex Luthor's allies, they could've been his slaves.
Superman II was fun to see in the theater.
