Kinda hard since for the most part, Lex has created Bizarro in both Pre-Crisis and Post-Crisis continuities. The only reason Superman IV didn't work was because A) the script was bad and B) they didn't use Bizarro but an incredibly bad simulation.

Though in his first appearence in Pre-Crisis continuity, he was not created by Lex Luthor, in nearly every subsequent appearence it has been Lex who created him. The only other time he wasn't involved was when Dabny Donovan created a couple in 1998 and in 2000, when the Joker had tricked Mr. Mxyzptlk into giving him nearl all of his power, which resulted in the creation of a varation of the Pre-Crisis Bizarro #1. However, when he will appear in the Richard Donner/Geoff Johns/Adam Kubert run on Action Comics, he will be much scarier than he has been in his history. Lex creating an imperfect clone of Superman known as Bizarro, though he doesn't have to be named that onscreen, can work. Then I suggest not even bothering to watch "The Man Of Steel", because you will be disappointed. Not every comic villian is campy. The Burton films were not ruined because of the costumed villians. Schumacher and Warner Brothers made Riddler, Two-Face, Mr. Freeze, Poison Ivy and Bane into a joke.

Bryan Singer, as noted, has done well with villians. Making Magneto, Toad, Sabertooth, Lady Deathstrike, Pyro and Mystique very serious and deadly. He did pretty good making Lex far more than he had been under Donner. I trust him to do well with either Bizarro or Brainiac. As to villians being alien, I guess you don't like Star Wars since not all aliens are human or human looking.
