WARNING: The following article contains major spoilers for Season 1 of Syfy's Krypton.
When Krypton was first announced, fans were skeptical about the series for a few reasons. For starters, the idea of a Superman-themed show set outside of the DC Extended Universe continuity which wouldn't impact on Henry Cavill's Kal-El felt a bit unnecessary. This feeling was heightened by the fact that early promos indicated it would be yet another dark, gritty story in an alternate DC reality.
And then there's the fact that the entire series' premise is based on an untold adventure of Kal-El's grandfather, Seg-El, who would be trying to preserve Superman's existence in the future. Choosing an unknown hero from the past seemed a sure-fire way to limit the villains available, but as details emerged, it was revealed that along with the House of Zod, Brainiac and Doomsday would be part of the show's narrative. And yet, as popular as these characters are, an air of apprehension remained. After all, fans still had bad memories of DC's villains already being mishandled in the DCEU.
Yes, the Arrowverse has had a fair amount of success with its villains, but remember: Krypton is not part of the Arrowverse. And yet, Syfy's new show has easily outperformed its CW brethren when it comes to intriguing bad guys. More importantly, it has so far trumped what Warner Bros. has done on the big screen, to the point where it's basically showing the studio how it should craft DC's most notorious miscreants.
Apart from Michael Shannon's General Dru-Zod in Man of Steel, the DCEU has lacked truly formidable nemeses. Shannon's Zod was intimidating, intense and merciless, which is why Superman controversially killed him. What made him resonate was that fans could relate to his mission to restore his planet -- this sense of empathy is what connects us to all Krypton's villains.
